Primitive Type u32

The 32-bit unsigned integer type.

Implementations

impl u32[src]

pub const MIN: u32[src]1.43.0

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

Examples

Basic usage:

assert_eq!(u32::MIN, 0);

pub const MAX: u32[src]1.43.0

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>[src]

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));

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).

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.

pub const fn wrapping_neg(self) -> u32[src]1.2.0

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);

#[must_use = "this returns the result of the operation, \ without modifying the original"]pub const fn wrapping_shl(self, rhs: u32) -> u32[src]1.2.0

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);

#[must_use = "this returns the result of the operation, \ without modifying the original"]pub const fn wrapping_shr(self, rhs: u32) -> u32[src]1.2.0

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.

Examples

Basic usage:

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

pub fn checked_next_power_of_two(self) -> Option<u32>[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!(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 fn wrapping_next_power_of_two(self) -> u32[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!(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][src]1.32.0

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][src]1.32.0

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][src]1.32.0

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[src]1.32.0

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[src]1.32.0

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[src]1.32.0

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[src]

This method is soft-deprecated.

Although using it won’t cause compilation warning, new code should use u32::MIN instead.

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

pub const fn max_value() -> u32[src]

This method is soft-deprecated.

Although using it won’t cause compilation warning, new code should use u32::MAX instead.

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