Primitive Type usize

1.0.0 ·
Expand description

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.

§Panics
§Overflow behavior

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

§Examples

Basic usage:

``````#![feature(strict_overflow_ops)]
assert_eq!((usize::MAX - 2).strict_add(1), usize::MAX - 1);``````

The following panics because of overflow:

``````#![feature(strict_overflow_ops)]

1.79.0 (const: 1.79.0) · source

pub const unsafe fn unchecked_add(self, rhs: Self) -> Self

Unchecked integer addition. Computes `self + rhs`, assuming overflow cannot occur.

Calling `x.unchecked_add(y)` is semantically equivalent to calling `x.``checked_add``(y).``unwrap_unchecked``()`.

If you’re just trying to avoid the panic in debug mode, then do not use this. Instead, you’re looking for `wrapping_add`.

§Safety

This results in undefined behavior when `self + rhs > usize::MAX` or `self + rhs < usize::MIN`, i.e. when `checked_add` would return `None`.

1.66.0 (const: 1.66.0) · source

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

§Examples

The following panics because of overflow:

``````#![feature(strict_overflow_ops)]
let _ = 0usize.strict_sub(1);``````
1.79.0 (const: 1.79.0) · source

pub const unsafe fn unchecked_sub(self, rhs: Self) -> Self

Unchecked integer subtraction. Computes `self - rhs`, assuming overflow cannot occur.

Calling `x.unchecked_sub(y)` is semantically equivalent to calling `x.``checked_sub``(y).``unwrap_unchecked``()`.

If you’re just trying to avoid the panic in debug mode, then do not use this. Instead, you’re looking for `wrapping_sub`.

If you find yourself writing code like this:

``````if foo >= bar {
// SAFETY: just checked it will not overflow
let diff = unsafe { foo.unchecked_sub(bar) };
// ... use diff ...
}``````

Consider changing it to

``````if let Some(diff) = foo.checked_sub(bar) {
// ... use diff ...
}``````

As that does exactly the same thing – including telling the optimizer that the subtraction cannot overflow – but avoids needing `unsafe`.

§Safety

This results in undefined behavior when `self - rhs > usize::MAX` or `self - rhs < usize::MIN`, i.e. when `checked_sub` would return `None`.

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

🔬This is a nightly-only experimental API. (`unsigned_signed_diff` #126041)

Strict Euclidean division. Computes `self.div_euclid(rhs)`.

Strict division on unsigned types is just normal division. There’s no way overflow could ever happen. This function exists so that all operations are accounted for in the strict operations. Since, for the positive integers, all common definitions of division are equal, this is exactly equal to `self.strict_div(rhs)`.

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 = 0x1234567890123456usize.to_ne_bytes();

§Examples

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

🔬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

Basic usage:

Please note that this example is shared between integer types. Which explains why `u32` is used here.

``````#![feature(bigint_helper_methods)]
assert_eq!(5u32.widening_mul(2), (10, 0));
assert_eq!(1_000_000_000u32.widening_mul(10), (1410065408, 2));``````
source

pub const fn carrying_mul(self, rhs: Self, carry: Self) -> (Self, Self)

🔬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

Basic usage:

Please note that this example is shared between integer types. Which explains why `u32` is used here.

``````#![feature(bigint_helper_methods)]
assert_eq!(5u32.carrying_mul(2, 0), (10, 0));
assert_eq!(5u32.carrying_mul(2, 10), (20, 0));
assert_eq!(1_000_000_000u32.carrying_mul(10, 0), (1410065408, 2));
assert_eq!(1_000_000_000u32.carrying_mul(10, 10), (1410065418, 2));
assert_eq!(usize::MAX.carrying_mul(usize::MAX, usize::MAX), (0, usize::MAX));``````

This is the core operation needed for scalar multiplication when implementing it for wider-than-native types.

``````#![feature(bigint_helper_methods)]
fn scalar_mul_eq(little_endian_digits: &mut Vec<u16>, multiplicand: u16) {
let mut carry = 0;
for d in little_endian_digits.iter_mut() {
(*d, carry) = d.carrying_mul(multiplicand, carry);
}
if carry != 0 {
little_endian_digits.push(carry);
}
}

let mut v = vec![10, 20];
scalar_mul_eq(&mut v, 3);
assert_eq!(v, [30, 60]);

assert_eq!(0x87654321_u64 * 0xFEED, 0x86D3D159E38D);
let mut v = vec![0x4321, 0x8765];
scalar_mul_eq(&mut v, 0xFEED);
assert_eq!(v, [0xE38D, 0xD159, 0x86D3]);``````

If `carry` is zero, this is similar to `overflowing_mul`, except that it gives the value of the overflow instead of just whether one happened:

``````#![feature(bigint_helper_methods)]
let r = u8::carrying_mul(7, 13, 0);
assert_eq!((r.0, r.1 != 0), u8::overflowing_mul(7, 13));
let r = u8::carrying_mul(13, 42, 0);
assert_eq!((r.0, r.1 != 0), u8::overflowing_mul(13, 42));``````

The value of the first field in the returned tuple matches what you’d get by combining the `wrapping_mul` and `wrapping_add` methods:

``````#![feature(bigint_helper_methods)]
assert_eq!(
789_u16.carrying_mul(456, 123).0,
);``````
source

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

🔬This is a nightly-only experimental API. (`num_midpoint` #110840)

Calculates the middle point of `self` and `rhs`.

`midpoint(a, b)` is `(a + b) >> 1` as if it were performed in a sufficiently-large signed integral type. This implies that the result is always rounded towards negative infinity and that no overflow will ever occur.

§Examples
``````#![feature(num_midpoint)]
assert_eq!(0usize.midpoint(4), 2);
assert_eq!(1usize.midpoint(4), 2);``````

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

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`
• `A-Z`
§Panics

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

§Examples

Basic usage:

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