Primitive Type isize

The pointer-sized signed integer type.

The size of this primitive is how many bytes it takes to reference any location in memory. For example, on a 32 bit target, this is 4 bytes and on a 64 bit target, this is 8 bytes.

Implementations

impl isize

pub const MIN: isize = -9_223_372_036_854_775_808isize

The smallest value that can be represented by this integer type (−2⁶³ on 64-bit targets).

Examples

assert_eq!(isize::MIN, -9223372036854775808);

pub const MAX: isize = 9_223_372_036_854_775_807isize

The largest value that can be represented by this integer type (2⁶³ − 1 on 64-bit targets).

Examples

assert_eq!(isize::MAX, 9223372036854775807);

pub const BITS: u32 = 64u32

The size of this integer type in bits.

Examples

assert_eq!(isize::BITS, 64);

pub const fn count_ones(self) -> u32

🔬This is a nightly-only experimental API. (strict_overflow_ops #118260)

Strict integer addition. Computes self + rhs, panicking if overflow occurred.

Panics

Overflow behavior

This function will always panic on overflow, regardless of whether overflow checks are enabled.

Examples

#![feature(strict_overflow_ops)]

pub const fn wrapping_div(self, rhs: isize) -> isize

Wrapping (modular) division. Computes self / rhs, wrapping around at the boundary of the type.

The only case where such wrapping can occur is when one divides MIN / -1 on a signed type (where MIN is the negative minimal value for the type); this is equivalent to -MIN, a positive value that is too large to represent in the type. In such a case, this function returns MIN itself.

Panics

This function will panic if rhs is zero.

Examples

assert_eq!(100isize.wrapping_div(10), 10);

pub const fn wrapping_div_euclid(self, rhs: isize) -> isize

Wrapping Euclidean division. Computes self.div_euclid(rhs), wrapping around at the boundary of the type.

Wrapping will only occur in MIN / -1 on a signed type (where MIN is the negative minimal value for the type). This is equivalent to -MIN, a positive value that is too large to represent in the type. In this case, this method returns MIN itself.

Panics

This function will panic if rhs is zero.

Examples

assert_eq!(100isize.wrapping_div_euclid(10), 10);

pub const fn wrapping_rem(self, rhs: isize) -> isize

Wrapping (modular) remainder. Computes self % rhs, wrapping around at the boundary of the type.

Such wrap-around never actually occurs mathematically; implementation artifacts make x % y invalid for MIN / -1 on a signed type (where MIN is the negative minimal value). In such a case, this function returns 0.

Panics

This function will panic if rhs is zero.

Examples

assert_eq!(100isize.wrapping_rem(10), 0);

pub const fn wrapping_rem_euclid(self, rhs: isize) -> isize

Wrapping (modular) negation. Computes -self, wrapping around at the boundary of the type.

Examples

assert_eq!(isize::MIN.wrapping_neg(), isize::MIN);

pub const fn wrapping_shl(self, rhs: u32) -> isize

Panic-free bitwise shift-left; yields self << mask(rhs), where mask removes any high-order bits of rhs that would cause the shift to exceed the bitwidth of the type.

Note that this is not the same as a rotate-left; the RHS of a wrapping shift-left is restricted to the range of the type, rather than the bits shifted out of the LHS being returned to the other end. The primitive integer types all implement a rotate_left function, which may be what you want instead.

Examples

assert_eq!((-1isize).wrapping_shl(7), -128);
assert_eq!((-1isize).wrapping_shl(128), -1);

pub const fn wrapping_shr(self, rhs: u32) -> isize

Panic-free bitwise shift-right; yields self >> mask(rhs), where mask removes any high-order bits of rhs that would cause the shift to exceed the bitwidth of the type.

Note that this is not the same as a rotate-right; the RHS of a wrapping shift-right is restricted to the range of the type, rather than the bits shifted out of the LHS being returned to the other end. The primitive integer types all implement a rotate_right function, which may be what you want instead.

pub const fn wrapping_abs(self) -> isize

Examples

assert_eq!(100isize.wrapping_abs(), 100);
assert_eq!((-100isize).wrapping_abs(), 100);
assert_eq!(isize::MIN.wrapping_abs(), isize::MIN);

pub const fn carrying_add(self, rhs: isize, carry: bool) -> (isize, bool)

🔬This is a nightly-only experimental API. (bigint_helper_methods #85532)

Calculates self + rhs + carry and checks for overflow.

Performs “ternary addition” of two integer operands and a carry-in bit, and returns a tuple of the sum along with a boolean indicating whether an arithmetic overflow would occur. On overflow, the wrapped value is returned.

This allows chaining together multiple additions to create a wider addition, and can be useful for bignum addition. This method should only be used for the most significant word; for the less significant words the unsigned method usize::carrying_add should be used.

The output boolean returned by this method is not a carry flag, and should not be added to a more significant word.

If the input carry is false, this method is equivalent to overflowing_add.

Examples

#![feature(bigint_helper_methods)]
// Only the most significant word is signed.
//
//   10  MAX    (a = 10 × 2^64 + 2^64 - 1)
// + -5    9    (b = -5 × 2^64 + 9)
// ---------
//    6    8    (sum = 6 × 2^64 + 8)

let (a1, a0): (isize, usize) = (10, usize::MAX);
let (b1, b0): (isize, usize) = (-5, 9);
let carry0 = false;

// usize::carrying_add for the less significant words
let (sum0, carry1) = a0.carrying_add(b0, carry0);
assert_eq!(carry1, true);

// isize::carrying_add for the most significant word
let (sum1, overflow) = a1.carrying_add(b1, carry1);
assert_eq!(overflow, false);

assert_eq!((sum1, sum0), (6, 8));

pub const fn overflowing_add_unsigned(self, rhs: usize) -> (isize, bool)

pub const fn overflowing_sub(self, rhs: isize) -> (isize, bool)

🔬This is a nightly-only experimental API. (bigint_helper_methods #85532)

Calculates self − rhs − borrow and checks for overflow.

Performs “ternary subtraction” by subtracting both an integer operand and a borrow-in bit from self, and returns a tuple of the difference along with a boolean indicating whether an arithmetic overflow would occur. On overflow, the wrapped value is returned.

This allows chaining together multiple subtractions to create a wider subtraction, and can be useful for bignum subtraction. This method should only be used for the most significant word; for the less significant words the unsigned method usize::borrowing_sub should be used.

The output boolean returned by this method is not a borrow flag, and should not be subtracted from a more significant word.

If the input borrow is false, this method is equivalent to overflowing_sub.

Examples

#![feature(bigint_helper_methods)]
// Only the most significant word is signed.
//
//    6    8    (a = 6 × 2^64 + 8)
// - -5    9    (b = -5 × 2^64 + 9)
// ---------
//   10  MAX    (diff = 10 × 2^64 + 2^64 - 1)

let (a1, a0): (isize, usize) = (6, 8);
let (b1, b0): (isize, usize) = (-5, 9);
let borrow0 = false;

// usize::borrowing_sub for the less significant words
let (diff0, borrow1) = a0.borrowing_sub(b0, borrow0);
assert_eq!(borrow1, true);

// isize::borrowing_sub for the most significant word
let (diff1, overflow) = a1.borrowing_sub(b1, borrow1);
assert_eq!(overflow, false);

assert_eq!((diff1, diff0), (10, usize::MAX));

pub const fn overflowing_sub_unsigned(self, rhs: usize) -> (isize, bool)

pub const fn overflowing_mul(self, rhs: isize) -> (isize, bool)

Calculates the multiplication of self and rhs.

assert_eq!(1_000_000_000i32.overflowing_mul(10), (1410065408, true));

pub const fn widening_mul(self, rhs: isize) -> (usize, isize)

🔬This is a nightly-only experimental API. (bigint_helper_methods #85532)

Calculates the complete product self * rhs without the possibility to overflow.

This returns the low-order (wrapping) bits and the high-order (overflow) bits of the result as two separate values, in that order.

If you also need to add a carry to the wide result, then you want Self::carrying_mul instead.

Examples

Please note that this example is shared between integer types. Which explains why i32 is used here.

#![feature(bigint_helper_methods)]
assert_eq!(5i32.widening_mul(-2), (4294967286, -1));
assert_eq!(1_000_000_000i32.widening_mul(-10), (2884901888, -3));

🔬This is a nightly-only experimental API. (bigint_helper_methods #85532)

Calculates the “full multiplication” self * rhs + carry without the possibility to overflow.

This returns the low-order (wrapping) bits and the high-order (overflow) bits of the result as two separate values, in that order.

Performs “long multiplication” which takes in an extra amount to add, and may return an additional amount of overflow. This allows for chaining together multiple multiplications to create “big integers” which represent larger values.

If you don’t need the carry, then you can use Self::widening_mul instead.

Examples

Please note that this example is shared between integer types. Which explains why i32 is used here.

#![feature(bigint_helper_methods)]
assert_eq!(5i32.carrying_mul(-2, 0), (4294967286, -1));
assert_eq!(5i32.carrying_mul(-2, 10), (0, 0));

🔬This is a nightly-only experimental API. (bigint_helper_methods #85532)

Calculates the “full multiplication” self * rhs + carry1 + carry2 without the possibility to overflow.

This returns the low-order (wrapping) bits and the high-order (overflow) bits of the result as two separate values, in that order.

Performs “long multiplication” which takes in an extra amount to add, and may return an additional amount of overflow. This allows for chaining together multiple multiplications to create “big integers” which represent larger values.

If you don’t need either carry, then you can use Self::widening_mul instead, and if you only need one carry, then you can use Self::carrying_mul instead.

Examples

Please note that this example is shared between integer types. Which explains why i32 is used here.

#![feature(bigint_helper_methods)]
assert_eq!(5i32.carrying_mul_add(-2, 0, 0), (4294967286, -1));
assert_eq!(5i32.carrying_mul_add(-2, 10, 10), (10, 0));

assert_eq!(isize::MIN.overflowing_neg(), (isize::MIN, true));

pub const fn overflowing_shl(self, rhs: u32) -> (isize, bool)

Shifts self left by rhs bits.

Returns a tuple of the shifted version of self along with a boolean indicating whether the shift value was larger than or equal to the number of bits. If the shift value is too large, then value is masked (N-1) where N is the number of bits, and this value is then used to perform the shift.

pub const fn overflowing_shr(self, rhs: u32) -> (isize, bool)

Shifts self right by rhs bits.

Returns a tuple of the shifted version of self along with a boolean indicating whether the shift value was larger than or equal to the number of bits. If the shift value is too large, then value is masked (N-1) where N is the number of bits, and this value is then used to perform the shift.

pub const fn div_euclid(self, rhs: isize) -> isize

Calculates the quotient of Euclidean division of self by rhs.

This computes the integer q such that self = q * rhs + r, with r = self.rem_euclid(rhs) and 0 <= r < abs(rhs).

In other words, the result is self / rhs rounded to the integer q such that self >= q * rhs. If self > 0, this is equal to rounding towards zero (the default in Rust); if self < 0, this is equal to rounding away from zero (towards +/- infinity). If rhs > 0, this is equal to rounding towards -infinity; if rhs < 0, this is equal to rounding towards +infinity.

Panics

This function will panic if rhs is zero or if self is Self::MIN and rhs is -1. This behavior is not affected by the overflow-checks flag.

Examples

let a: isize = 7; // or any other integer type
let b = 4;

assert_eq!(a.div_euclid(b), 1); // 7 >= 4 * 1
assert_eq!(a.div_euclid(-b), -1); // 7 >= -4 * -1
assert_eq!((-a).div_euclid(b), -2); // -7 >= 4 * -2
assert_eq!((-a).div_euclid(-b), 2); // -7 >= -4 * 2

pub const fn rem_euclid(self, rhs: isize) -> isize

Calculates the least nonnegative remainder of self (mod rhs).

This is done as if by the Euclidean division algorithm – given r = self.rem_euclid(rhs), the result satisfies self = rhs * self.div_euclid(rhs) + r and 0 <= r < abs(rhs).

Panics

This function will panic if rhs is zero or if self is Self::MIN and rhs is -1. This behavior is not affected by the overflow-checks flag.

Examples

let a: isize = 7; // or any other integer type
let b = 4;

assert_eq!(a.rem_euclid(b), 3);
assert_eq!((-a).rem_euclid(b), 1);
assert_eq!(a.rem_euclid(-b), 3);
assert_eq!((-a).rem_euclid(-b), 1);

This will panic:

This function will panic if rhs is zero or if self is Self::MIN and rhs is -1. This behavior is not affected by the overflow-checks flag.

Examples

#![feature(int_roundings)]
let a: isize = 8;
let b = 3;

assert_eq!(a.div_ceil(b), 3);
assert_eq!(a.div_ceil(-b), -2);
assert_eq!((-a).div_ceil(b), -2);
assert_eq!((-a).div_ceil(-b), 3);

pub const fn next_multiple_of(self, rhs: isize) -> isize

🔬This is a nightly-only experimental API. (int_roundings #88581)

If rhs is positive, calculates the smallest value greater than or equal to self that is a multiple of rhs. If rhs is negative, calculates the largest value less than or equal to self that is a multiple of rhs.

Panics

This function will panic if rhs is zero.

Overflow behavior

On overflow, this function will panic if overflow checks are enabled (default in debug mode) and wrap if overflow checks are disabled (default in release mode).

Examples

#![feature(int_roundings)]
assert_eq!(16_isize.next_multiple_of(8), 16);
assert_eq!(23_isize.next_multiple_of(8), 24);
assert_eq!(16_isize.next_multiple_of(-8), 16);
assert_eq!(23_isize.next_multiple_of(-8), 16);
assert_eq!((-16_isize).next_multiple_of(8), -16);
assert_eq!((-23_isize).next_multiple_of(8), -16);
assert_eq!((-16_isize).next_multiple_of(-8), -16);
assert_eq!((-23_isize).next_multiple_of(-8), -24);

pub const fn checked_next_multiple_of(self, rhs: isize) -> Option<isize>

🔬This is a nightly-only experimental API. (int_roundings #88581)

If rhs is positive, calculates the smallest value greater than or equal to self that is a multiple of rhs. If rhs is negative, calculates the largest value less than or equal to self that is a multiple of rhs. Returns None if rhs is zero or the operation would result in overflow.

Examples

#![feature(int_roundings)]
assert_eq!(16_isize.checked_next_multiple_of(8), Some(16));
assert_eq!(23_isize.checked_next_multiple_of(8), Some(24));
assert_eq!(16_isize.checked_next_multiple_of(-8), Some(16));
assert_eq!(23_isize.checked_next_multiple_of(-8), Some(16));
assert_eq!((-16_isize).checked_next_multiple_of(8), Some(-16));
assert_eq!((-23_isize).checked_next_multiple_of(8), Some(-16));
assert_eq!((-16_isize).checked_next_multiple_of(-8), Some(-16));
assert_eq!((-23_isize).checked_next_multiple_of(-8), Some(-24));
assert_eq!(1_isize.checked_next_multiple_of(0), None);
assert_eq!(isize::MAX.checked_next_multiple_of(2), None);

pub const fn ilog(self, base: isize) -> u32

Returns the logarithm of the number with respect to an arbitrary base, rounded down.

This method might not be optimized owing to implementation details; ilog2 can produce results more efficiently for base 2, and ilog10 can produce results more efficiently for base 10.

Panics

This function will panic if self is less than or equal to zero, or if base is less than 2.

Examples

assert_eq!(5isize.ilog(5), 1);

pub const fn ilog2(self) -> u32

Returns the base 2 logarithm of the number, rounded down.

Panics

This function will panic if self is less than or equal to zero.

Examples

assert_eq!(2isize.ilog2(), 1);

pub const fn ilog10(self) -> u32

Returns the base 10 logarithm of the number, rounded down.

Panics

This function will panic if self is less than or equal to zero.

Example

assert_eq!(10isize.ilog10(), 1);

pub const fn checked_ilog(self, base: isize) -> Option<u32>

Returns the logarithm of the number with respect to an arbitrary base, rounded down.

Returns None if the number is negative or zero, or if the base is not at least 2.

This method might not be optimized owing to implementation details; checked_ilog2 can produce results more efficiently for base 2, and checked_ilog10 can produce results more efficiently for base 10.

Examples

assert_eq!(5isize.checked_ilog(5), Some(1));

pub const fn checked_ilog2(self) -> Option<u32>

Returns the base 2 logarithm of the number, rounded down.

Returns None if the number is negative or zero.

Examples

assert_eq!(2isize.checked_ilog2(), Some(1));

pub const fn checked_ilog10(self) -> Option<u32>

Returns the base 10 logarithm of the number, rounded down.

Returns None if the number is negative or zero.

Example

assert_eq!(10isize.checked_ilog10(), Some(1));

pub const fn abs(self) -> isize

Computes the absolute value of self.

Overflow behavior

The absolute value of isize::MIN cannot be represented as an isize, and attempting to calculate it will cause an overflow. This means that code in debug mode will trigger a panic on this case and optimized code will return isize::MIN without a panic. If you do not want this behavior, consider using unsigned_abs instead.

Examples

assert_eq!(10isize.abs(), 10);
assert_eq!((-10isize).abs(), 10);

pub const fn abs_diff(self, other: isize) -> usize

Computes the absolute difference between self and other.

This function always returns the correct answer without overflow or panics by returning an unsigned integer.

Examples

assert_eq!(100isize.abs_diff(80), 20usize);
assert_eq!(100isize.abs_diff(110), 10usize);
assert_eq!((-100isize).abs_diff(80), 180usize);
assert_eq!((-100isize).abs_diff(-120), 20usize);
assert_eq!(isize::MIN.abs_diff(isize::MAX), usize::MAX);

pub const fn signum(self) -> isize

Returns a number representing sign of self.

• 0 if the number is zero
• 1 if the number is positive
• -1 if the number is negative

Examples

assert_eq!(10isize.signum(), 1);
assert_eq!(0isize.signum(), 0);
assert_eq!((-10isize).signum(), -1);

pub const fn is_positive(self) -> bool

Returns true if self is positive and false if the number is zero or negative.

Examples

assert!(10isize.is_positive());
assert!(!(-10isize).is_positive());

pub const fn is_negative(self) -> bool

Returns true if self is negative and false if the number is zero or positive.

Examples

assert!((-10isize).is_negative());
assert!(!10isize.is_negative());

pub const fn to_be_bytes(self) -> [u8; 8]

Returns the memory representation of this integer as a byte array in big-endian (network) byte order.

Note: This function returns an array of length 2, 4 or 8 bytes depending on the target pointer size.

Examples

let bytes = 0x1234567890123456isize.to_be_bytes();
assert_eq!(bytes, [0x12, 0x34, 0x56, 0x78, 0x90, 0x12, 0x34, 0x56]);

pub const fn to_le_bytes(self) -> [u8; 8]

Returns the memory representation of this integer as a byte array in little-endian byte order.

Note: This function returns an array of length 2, 4 or 8 bytes depending on the target pointer size.

Examples

let bytes = 0x1234567890123456isize.to_le_bytes();
assert_eq!(bytes, [0x56, 0x34, 0x12, 0x90, 0x78, 0x56, 0x34, 0x12]);

pub const fn to_ne_bytes(self) -> [u8; 8]

Returns the memory representation of this integer as a byte array in native byte order.

As the target platform’s native endianness is used, portable code should use to_be_bytes or to_le_bytes, as appropriate, instead.

Note: This function returns an array of length 2, 4 or 8 bytes depending on the target pointer size.

Examples

let bytes = 0x1234567890123456isize.to_ne_bytes();
assert_eq!(
    bytes,
    if cfg!(target_endian = "big") {
        [0x12, 0x34, 0x56, 0x78, 0x90, 0x12, 0x34, 0x56]
    } else {
        [0x56, 0x34, 0x12, 0x90, 0x78, 0x56, 0x34, 0x12]
    }
);

pub const fn from_be_bytes(bytes: [u8; 8]) -> isize

Creates an integer value from its representation as a byte array in big endian.

Examples

let value = isize::from_be_bytes([0x12, 0x34, 0x56, 0x78, 0x90, 0x12, 0x34, 0x56]);
assert_eq!(value, 0x1234567890123456);

When starting from a slice rather than an array, fallible conversion APIs can be used:

fn read_be_isize(input: &mut &[u8]) -> isize {
    let (int_bytes, rest) = input.split_at(size_of::<isize>());
    *input = rest;
    isize::from_be_bytes(int_bytes.try_into().unwrap())
}

pub const fn from_le_bytes(bytes: [u8; 8]) -> isize

Creates an integer value from its representation as a byte array in little endian.

Note: This function takes an array of length 2, 4 or 8 bytes depending on the target pointer size.

Examples

let value = isize::from_le_bytes([0x56, 0x34, 0x12, 0x90, 0x78, 0x56, 0x34, 0x12]);
assert_eq!(value, 0x1234567890123456);

When starting from a slice rather than an array, fallible conversion APIs can be used:

fn read_le_isize(input: &mut &[u8]) -> isize {
    let (int_bytes, rest) = input.split_at(size_of::<isize>());
    *input = rest;
    isize::from_le_bytes(int_bytes.try_into().unwrap())
}

pub const fn from_ne_bytes(bytes: [u8; 8]) -> isize

Creates an integer value from its memory representation as a byte array in native endianness.

As the target platform’s native endianness is used, portable code likely wants to use from_be_bytes or from_le_bytes, as appropriate instead.

Note: This function takes an array of length 2, 4 or 8 bytes depending on the target pointer size.

Examples

let value = isize::from_ne_bytes(if cfg!(target_endian = "big") {
    [0x12, 0x34, 0x56, 0x78, 0x90, 0x12, 0x34, 0x56]
} else {
    [0x56, 0x34, 0x12, 0x90, 0x78, 0x56, 0x34, 0x12]
});
assert_eq!(value, 0x1234567890123456);

When starting from a slice rather than an array, fallible conversion APIs can be used:

fn read_ne_isize(input: &mut &[u8]) -> isize {
    let (int_bytes, rest) = input.split_at(size_of::<isize>());
    *input = rest;
    isize::from_ne_bytes(int_bytes.try_into().unwrap())
}

pub const fn min_value() -> isize

👎Deprecating in a future version: replaced by the MIN associated constant on this type

New code should prefer to use isize::MIN instead.

Returns the smallest value that can be represented by this integer type.

pub const fn max_value() -> isize

👎Deprecating in a future version: replaced by the MAX associated constant on this type

New code should prefer to use isize::MAX instead.

Returns the largest value that can be represented by this integer type.

pub const fn midpoint(self, rhs: isize) -> isize

Calculates the midpoint (average) between self and rhs.

midpoint(a, b) is (a + b) / 2 as if it were performed in a sufficiently-large signed integral type. This implies that the result is always rounded towards zero and that no overflow will ever occur.

Examples

assert_eq!(0isize.midpoint(4), 2);
assert_eq!((-1isize).midpoint(2), 0);
assert_eq!((-7isize).midpoint(0), -3);
assert_eq!(0isize.midpoint(-7), -3);
assert_eq!(0isize.midpoint(7), 3);

impl isize

pub const fn from_str_radix( src: &str, radix: u32, ) -> Result<isize, ParseIntError>

Parses an integer from a string slice with digits in a given base.

The string is expected to be an optional + or - sign followed by only digits. Leading and trailing non-digit characters (including whitespace) represent an error. Underscores (which are accepted in Rust literals) also represent an error.

Digits are a subset of these characters, depending on radix:

• 0-9
• a-z
• A-Z

Panics

This function panics if radix is not in the range from 2 to 36.

Examples

assert_eq!(isize::from_str_radix("A", 16), Ok(10));

Trailing space returns error:

assert!(isize::from_str_radix("1 ", 10).is_err());

🔬This is a nightly-only experimental API. (int_from_ascii #134821)

Parses an integer from an ASCII-byte slice with decimal digits.

The characters are expected to be an optional + or - sign followed by only digits. Leading and trailing non-digit characters (including whitespace) represent an error. Underscores (which are accepted in Rust literals) also represent an error.

Examples

#![feature(int_from_ascii)]

assert_eq!(isize::from_ascii(b"+10"), Ok(10));

Trailing space returns error:

assert!(isize::from_ascii(b"1 ").is_err());

pub const fn from_ascii_radix( src: &[u8], radix: u32, ) -> Result<isize, ParseIntError>

🔬This is a nightly-only experimental API. (int_from_ascii #134821)

impl isize

pub fn format_into(self, buf: &mut NumBuffer<isize>) -> &str

🔬This is a nightly-only experimental API. (int_format_into #138215)

Examples

#![feature(int_format_into)]
use core::fmt::NumBuffer;

let n = 0isize;
let mut buf = NumBuffer::new();
assert_eq!(n.format_into(&mut buf), "0");

let n1 = 32isize;
