# 1.0.0[−]Primitive Type u32

The 32-bit unsigned integer type.

See also the `std::u32` module.

## Methods

### `impl u32`[src]

#### `pub const fn min_value() -> u32`[src]

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

# Examples

Basic usage:

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

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

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>`[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.

1.2.0
[src]

Wrapping (modular) division. Computes `self / 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.

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)`.

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)`.

# Examples

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

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!((-128i8).wrapping_neg(), -128);Run

#### `pub const fn wrapping_shl(self, rhs: u32) -> u32`
1.2.0
[src]

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);Run

#### `pub const fn wrapping_shr(self, rhs: u32) -> u32`
1.2.0
[src]

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 next_power_of_two(self) -> u32`[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!(2u32.next_power_of_two(), 2);
    assert_eq!(3u32.next_power_of_two(), 4);Run

#### `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_value().checked_next_power_of_two(), None);Run

#### `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);

#### `pub fn to_be_bytes(self) -> [u8; 4]`
1.32.0
[src]

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]);Run

#### `pub fn to_le_bytes(self) -> [u8; 4]`
1.32.0
[src]

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]);Run

#### `pub fn to_ne_bytes(self) -> [u8; 4]`
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.

# Examples

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

            [0x78, 0x56, 0x34, 0x12]
        });Run

#### `pub fn from_be_bytes(bytes: [u8; 4]) -> u32`
1.32.0
[src]

Create an 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);Run

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

    #![feature(try_from)]
    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())
    }Run

#### `pub fn from_le_bytes(bytes: [u8; 4]) -> u32`
1.32.0
[src]

Create an 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);Run

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

    #![feature(try_from)]
    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())
    }Run

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

# 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);Run

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

#### `fn from(ip: Ipv4Addr) -> u32`[src]

Convert an `Ipv4Addr` into a host byte order `u32`.

# Examples

    use std::net::Ipv4Addr;

    let addr = Ipv4Addr::new(13, 12, 11, 10);
    assert_eq!(0x0d0c0b0au32, u32::from(addr));Run

## Search Tricks

Prefix searches with a type followed by a colon (e.g., `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g., `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
