# 1.0.0[−]Primitive Type usize

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**: usize

1.43.0[src]

**MIN**: usize

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

# Examples

Basic usage:

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

`pub const `**MAX**: usize

1.43.0[src]

**MAX**: usize

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

`0-9`

`a-z`

`A-Z`

is not in the range from 2 to 36.

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

assert_eq!(0x1usize.overflowing_shl(4), (0x10, false)); assert_eq!(0x1usize.overflowing_shl(132), (0x10, true));Run

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

1.7.0[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 =

```

1.34.0[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 fn pow(self, exp: u32) -> usize
```

[src]

Raises self to the power of `exp`

, using exponentiation by squaring.

# Examples

Basic usage:

assert_eq!(2usize.pow(5), 32);Run

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

1.38.0[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 typeRun

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

1.38.0[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 typeRun

`pub const fn is_power_of_two(self) -> bool`

[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 fn next_power_of_two(self) -> usize`

[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 fn checked_next_power_of_two(self) -> Option<usize>`

[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 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

Basic usage:

#![feature(wrapping_next_power_of_two)] assert_eq!(2usize.wrapping_next_power_of_two(), 2); assert_eq!(3usize.wrapping_next_power_of_two(), 4); assert_eq!(usize::MAX.wrapping_next_power_of_two(), 0);Run

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

1.32.0[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

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

1.32.0[src]

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

# Examples

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

1.32.0[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

let bytes = 0x1234567890123456usize.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] } );Run

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

1.32.0[src]

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

use std::convert::TryInto; fn read_be_usize(input: &mut &[u8]) -> usize { let (int_bytes, rest) = input.split_at(std::mem::size_of::<usize>()); *input = rest; usize::from_be_bytes(int_bytes.try_into().unwrap()) }Run

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

1.32.0[src]

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

# Examples

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

1.32.0[src]

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

`pub const fn min_value() -> usize`

[src]

**This method is soft-deprecated.**
