Primitive Type usize1.0.0[]

The pointer-sized unsigned 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 usize[src]

pub const MIN: usize1.43.0[src]

The smallest value that can be represented by this integer type.

Examples

Basic usage:

assert_eq!(usize::MIN, 0);
Run

pub const MAX: usize1.43.0[src]

The largest value that can be represented by this integer type.

Examples

Basic usage:

assert_eq!(usize::MAX, 18446744073709551615);
Run

pub const BITS: u321.53.0[src]

Run

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

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

The string is expected to be an optional + 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

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

This function exists, so that all operations are accounted for in the wrapping operations. Since, for the positive integers, all common definitions of division are equal, this is exactly equal to self.wrapping_div(rhs).

Run

pub const fn wrapping_neg(self) -> usize1.2.0 (const: 1.32.0)[src]

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

Since unsigned types do not have negative equivalents all applications of this function will wrap (except for -0). For values smaller than the corresponding signed type’s maximum the result is the same as casting the corresponding signed value. Any larger values are equivalent to MAX + 1 - (val - MAX - 1) where MAX is the corresponding signed type’s maximum.

Examples

Basic usage:

Please note that this example is shared between integer types. Which explains why i8 is used here.

assert_eq!(100i8.wrapping_neg(), -100);
assert_eq!((-128i8).wrapping_neg(), -128);

#[must_use = "this returns the result of the operation, \ without modifying the original"]
pub const fn wrapping_shl(self, rhs: u32) -> usize
1.2.0 (const: 1.32.0)[src]

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!(1usize.wrapping_shl(7), 128);
assert_eq!(1usize.wrapping_shl(128), 1);
Run

pub const fn overflowing_shr(self, rhs: u32) -> (usize, bool)
1.7.0 (const: 1.32.0)[src]

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.

Examples

Basic usage

assert_eq!(0x10usize.overflowing_shr(4), (0x1, false));
assert_eq!(0x10usize.overflowing_shr(132), (0x1, true));
Run

#[must_use = "this returns the result of the operation, \ without modifying the original"]
pub const fn overflowing_pow(self, exp: u32) -> (usize, bool)
1.34.0 (const: 1.50.0)[src]

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

Returns a tuple of the exponentiation along with a bool indicating whether an overflow happened.

Examples

Basic usage:

assert_eq!(3usize.overflowing_pow(5), (243, false));
assert_eq!(3u8.overflowing_pow(6), (217, true));
Run

#[must_use = "this returns the result of the operation, \ without modifying the original"]
pub const fn pow(self, exp: u32) -> usize
1.0.0 (const: 1.50.0)[src]

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

Examples

Basic usage:

Run

#[must_use = "this returns the result of the operation, \ without modifying the original"]
pub const fn div_euclid(self, rhs: usize) -> usize
1.38.0 (const: 1.52.0)[src]

Performs Euclidean division.

Since, for the positive integers, all common definitions of division are equal, this is exactly equal to self / rhs.

Panics

This function will panic if rhs is 0.

Examples

Basic usage:

assert_eq!(7usize.div_euclid(4), 1); // or any other integer type
Run

#[must_use = "this returns the result of the operation, \ without modifying the original"]
pub const fn rem_euclid(self, rhs: usize) -> usize
1.38.0 (const: 1.52.0)[src]

Calculates the least remainder of self (mod rhs).

Since, for the positive integers, all common definitions of division are equal, this is exactly equal to self % rhs.

Panics

This function will panic if rhs is 0.

Examples

Basic usage:

assert_eq!(7usize.rem_euclid(4), 3); // or any other integer type
Run

pub const fn is_power_of_two(self) -> bool1.0.0 (const: 1.32.0)[src]

Returns true if and only if self == 2^k for some k.

Examples

Basic usage:

assert!(16usize.is_power_of_two());
assert!(!10usize.is_power_of_two());
Run

pub const fn next_power_of_two(self) -> usize1.0.0 (const: 1.50.0)[src]

Returns the smallest power of two greater than or equal to self.

When return value overflows (i.e., self > (1 << (N-1)) for type uN), it panics in debug mode and return value is wrapped to 0 in release mode (the only situation in which method can return 0).

Examples

Basic usage:

assert_eq!(2usize.next_power_of_two(), 2);
assert_eq!(3usize.next_power_of_two(), 4);
Run

pub const fn checked_next_power_of_two(self) -> Option<usize>1.0.0 (const: 1.50.0)[src]

Returns the smallest power of two greater than or equal to n. If the next power of two is greater than the type’s maximum value, None is returned, otherwise the power of two is wrapped in Some.

Examples

Basic usage:

assert_eq!(2usize.checked_next_power_of_two(), Some(2));
assert_eq!(3usize.checked_next_power_of_two(), Some(4));
assert_eq!(usize::MAX.checked_next_power_of_two(), None);
Run

pub const fn wrapping_next_power_of_two(self) -> usize[src]

🔬 This is a nightly-only experimental API. (wrapping_next_power_of_two #32463)

needs decision on wrapping behaviour

Returns the smallest power of two greater than or equal to n. If the next power of two is greater than the type’s maximum value, the return value is wrapped to 0.

Examples

pub const fn to_be_bytes(self) -> [u8; 8]1.32.0 (const: 1.44.0)[src]

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 = 0x1234567890123456usize.to_be_bytes();
assert_eq!(bytes, [0x12, 0x34, 0x56, 0x78, 0x90, 0x12, 0x34, 0x56]);
Run

Examples

Run

pub const fn to_ne_bytes(self) -> [u8; 8]1.32.0 (const: 1.44.0)[src]

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
