Wrapping Euclidean modulo. Computes self.rem_euclid(rhs). Wrapped modulo calculation on unsigned types is just the regular remainder calculation. There’s no way wrapping could ever happen. This function exists, so that all operations are accounted for in the wrapping operations.

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);

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

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!(1u32.wrapping_shl(128), 1);

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

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!(2u32.checked_next_power_of_two(), Some(2));
assert_eq!(3u32.checked_next_power_of_two(), Some(4));
assert_eq!(u32::MAX.checked_next_power_of_two(), None);

pub const fn wrapping_next_power_of_two(self) -> u32

🔬 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!(2u32.wrapping_next_power_of_two(), 2);
assert_eq!(3u32.wrapping_next_power_of_two(), 4);

pub const fn to_be_bytes(self) -> [u8; 4]

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

Examples

let bytes = 0x12345678u32.to_be_bytes();
assert_eq!(bytes, [0x12, 0x34, 0x56, 0x78]);

pub const fn to_le_bytes(self) -> [u8; 4]

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

Examples

let bytes = 0x12345678u32.to_le_bytes();
assert_eq!(bytes, [0x78, 0x56, 0x34, 0x12]);

pub const fn to_ne_bytes(self) -> [u8; 4]

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.

Examples

let bytes = 0x12345678u32.to_ne_bytes();
assert_eq!(
    bytes,
    if cfg!(target_endian = "big") {
        [0x12, 0x34, 0x56, 0x78]
    } else {
        [0x78, 0x56, 0x34, 0x12]
    }
);

pub const fn from_be_bytes(bytes: [u8; 4]) -> u32

Create a native endian integer value from its representation as a byte array in big endian.

Examples

let value = u32::from_be_bytes([0x12, 0x34, 0x56, 0x78]);
assert_eq!(value, 0x12345678);

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

use std::convert::TryInto;

fn read_be_u32(input: &mut &[u8]) -> u32 {
    let (int_bytes, rest) = input.split_at(std::mem::size_of::<u32>());
    *input = rest;
    u32::from_be_bytes(int_bytes.try_into().unwrap())
}

pub const fn from_le_bytes(bytes: [u8; 4]) -> u32

Create a native endian integer value from its representation as a byte array in little endian.

Examples

let value = u32::from_le_bytes([0x78, 0x56, 0x34, 0x12]);
assert_eq!(value, 0x12345678);

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

use std::convert::TryInto;

fn read_le_u32(input: &mut &[u8]) -> u32 {
    let (int_bytes, rest) = input.split_at(std::mem::size_of::<u32>());
    *input = rest;
    u32::from_le_bytes(int_bytes.try_into().unwrap())
}

pub const fn from_ne_bytes(bytes: [u8; 4]) -> u32

Create a native endian 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.

Examples

let value = u32::from_ne_bytes(if cfg!(target_endian = "big") {
    [0x12, 0x34, 0x56, 0x78]
} else {
    [0x78, 0x56, 0x34, 0x12]
});
assert_eq!(value, 0x12345678);

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

use std::convert::TryInto;

fn read_ne_u32(input: &mut &[u8]) -> u32 {
    let (int_bytes, rest) = input.split_at(std::mem::size_of::<u32>());
    *input = rest;
    u32::from_ne_bytes(int_bytes.try_into().unwrap())
}

pub const fn min_value() -> u32

👎 Deprecating in a future Rust version:

replaced by the MIN associated constant on this type

New code should prefer to use u32::MIN instead.

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

pub const fn max_value() -> u32

👎 Deprecating in a future Rust version:

replaced by the MAX associated constant on this type

New code should prefer to use u32::MAX instead.

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