Struct `U32`

struct U32<O>(_, _)

A 32-bit unsigned integer stored in a given byte order.

U32 is like the native u32 type with two major differences: First, it has no alignment requirement (its alignment is 1). Second, the endianness of its memory layout is given by the type parameter O, which can be any type which implements ByteOrder. In particular, this refers to BigEndian, LittleEndian, NativeEndian, and NetworkEndian.

A U32 can be constructed using the new method, and its contained value can be obtained as a native u32 using the get method, or updated in place with the set method. In all cases, if the endianness O is not the same as the endianness of the current platform, an endianness swap will be performed in order to uphold the invariants that a) the layout of U32 has endianness O and that, b) the layout of u32 has the platform's native endianness.

U32 implements FromBytes, IntoBytes, and Unaligned, making it useful for parsing and serialization. See the module documentation for an example of how it can be used for parsing UDP packets.

Implementations

`impl<O> U32<O>`

const fn from_bytes(bytes: [u8; 4]) -> U32<O>

Constructs a new value from bytes which are already in O byte order.

const fn to_bytes(self: Self) -> [u8; 4]

Extracts the bytes of self without swapping the byte order.

The returned bytes will be in O byte order.

`impl<O: ByteOrder> U32<O>`

const fn new(n: u32) -> U32<O>: Constructs a new value, possibly performing an endianness swap to guarantee that the returned value has endianness O.
const fn get(self: Self) -> u32: Returns the value as a primitive type, possibly performing an endianness swap to guarantee that the return value has the endianness of the native platform.
fn set(self: &mut Self, n: u32): Updates the value in place as a primitive type, possibly performing an endianness swap to guarantee that the stored value has the endianness O.
