Primitive Type u32
The 32-bit unsigned integer type.
Implementations
impl u32
pub fn widening_mul(self, rhs: u32) -> (u32, u32)
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.
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));
pub fn carrying_mul(self, rhs: u32, carry: u32) -> (u32, u32)
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.

is the corresponding signed type’s maximum.

Shifts self left 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!(0x1u32.overflowing_shl(4), (0x10, false)); assert_eq!(0x1u32.overflowing_shl(132), (0x10, true));
pub const fn overflowing_shr(self, rhs: u32) -> (u32, bool)
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

pub const fn div_euclid(self, rhs: u32) -> u32
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!(7u32.div_euclid(4), 1); // or any other integer type
pub const fn rem_euclid(self, rhs: u32) -> u32
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!(7u32.rem_euclid(4), 3); // or any other integer type
pub const fn unstable_div_floor(self, rhs: u32) -> u32
Calculates the quotient of self
and rhs
, rounding the result towards negative infinity.
This is the same as performing self / rhs
for all unsigned integers.
Panics

is 0 or the operation results in overflow.
Examples
Basic usage:
#![feature(int_roundings)] assert_eq!(16_u32.unstable_next_multiple_of(8), 16); assert_eq!(23_u32.unstable_next_multiple_of(8), 24);
pub const fn checked_next_multiple_of(self, rhs: u32) -> Option<u32>
Calculates the smallest value greater than or equal to self
that is a multiple of rhs
. If rhs
is negative,
Examples
Basic usage:
#![feature(int_roundings)] assert_eq!(16_u32.checked_next_multiple_of(8), Some(16)); assert_eq!(23_u32.checked_next_multiple_of(8), Some(24)); assert_eq!(1_u32.checked_next_multiple_of(0), None); assert_eq!(u32::MAX.checked_next_multiple_of(2), None);
pub const fn is_power_of_two(self) -> bool
Returns true
if and only if self == 2^k
for some k
.
Examples
Basic usage:
assert!(16u32.is_power_of_two()); assert!(!10u32.is_power_of_two());
pub const fn next_power_of_two(self) -> u32
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!(2u32.next_power_of_two(), 2); assert_eq!(3u32.next_power_of_two(), 4);
pub const fn checked_next_power_of_two(self) -> Option<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
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); assert_eq!(u32::MAX.wrapping_next_power_of_two(), 0);
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
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
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.
