Primitive Type u32

The 32-bit unsigned integer type.

See also the std::u32 module.

Methods

impl u32

pub const fn min_value() -> u32

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

Examples

Basic usage:

assert_eq!(u32::min_value(), 0);

pub const fn max_value() -> u32

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

Examples

Basic usage:

pub fn from_str_radix(src: &str, radix: u32) -> Result<u32, 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!(u32::from_str_radix("A", 16), Ok(10));

Wrapping Euclidean division. Computes self.div_euclid(rhs). Wrapped division on unsigned types is just normal division. There's no way wrapping could ever happen. 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).

pub fn wrapping_rem(self, rhs: u32) -> u32

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_rem(rhs).

pub const fn wrapping_neg(self) -> u32

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);

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(7), 128);
assert_eq!(1u32.wrapping_shl(128), 1);

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

Panic-free bitwise shift-right; 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-right; the RHS of a wrapping shift-right 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_right function, which may be what you want instead.

pub fn overflowing_div_euclid(self, rhs: u32) -> (u32, bool)

Examples

Basic usage:

assert_eq!(2u32.next_power_of_two(), 2);
assert_eq!(3u32.next_power_of_two(), 4);

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

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.

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_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())
}
