Primitive Type isize

The pointer-sized signed integer type.

See also the std::isize module.

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.

Methods

impl isize

pub const fn min_value() -> isize

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

Examples

Basic usage:

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

pub const fn max_value() -> isize

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

Examples

Basic usage:

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

Converts a string slice in a given base to an integer.

The string is expected to be an optional + or - sign followed by digits. Leading and trailing whitespace 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

Basic usage:

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

#[must_use = "this returns the result of the operation, without modifying the original"] pub 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 0.

Examples

Basic usage:

assert_eq!(100isize.wrapping_div(10), 10);
assert_eq!((-128i8).wrapping_div(-1), -128);

#[must_use = "this returns the result of the operation, without modifying the original"] pub 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 0.

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 0.

Examples

Basic usage:

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

Wrapping will only occur in MIN % -1 on a signed type (where MIN is the negative minimal value for the type). In this case, this method returns 0.

This function will panic if rhs is 0.

Examples

Basic usage:

assert_eq!(100isize.wrapping_rem_euclid(10), 0);
assert_eq!((-128i8).wrapping_rem_euclid(-1), 0);

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

#[must_use = "this returns the result of the operation, without modifying the original"] 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

Basic usage:

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

The only case where such wrapping can occur is when one takes the absolute value of the negative minimal value for the type this is a positive value that is too large to represent in the type. In such a case, this function returns MIN itself.

Examples

Basic usage:

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

#[must_use = "this returns the result of the operation, without modifying the original"] pub fn pow(self, exp: u32) -> isize

Raises self to the power of exp, using exponentiation by squaring.

Examples

Basic usage:

let x: isize = 2; // or any other integer type

assert_eq!(x.pow(5), 32);

#[must_use = "this returns the result of the operation, without modifying the original"] pub fn div_euclid(self, rhs: isize) -> isize

Calculates the quotient of Euclidean division of self by rhs.

This computes the integer n such that self = n * rhs + self.rem_euclid(rhs), with 0 <= self.rem_euclid(rhs) < rhs.

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

Panics

This function will panic if rhs is 0 or the division results in overflow.

Examples

Basic usage:

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

#[must_use = "this returns the result of the operation, without modifying the original"] pub 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), self = rhs * self.div_euclid(rhs) + r, and 0 <= r < abs(rhs).

Panics

This function will panic if rhs is 0 or the division results in overflow.

Examples

Basic usage:

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);

pub const fn abs(self) -> isize

Computes the absolute value of self.

Overflow behavior

The absolute value of isize::min_value() 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_value() without a panic.

Examples

Basic usage:

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

pub 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

Basic usage:

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

Basic usage:

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

Basic usage:

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

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

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

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

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

Create an integer value from its representation as a byte array in big 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_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:

use std::convert::TryInto;

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

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

Create 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:

use std::convert::TryInto;

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

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

Create 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:

use std::convert::TryInto;

    *input = rest;
    isize::from_ne_bytes(int_bytes.try_into().unwrap())
