pub struct U32<O: ByteOrder>(/* private fields */);Expand description
A 32-bit unsigned integer
stored in O 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.
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, AsBytes, 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§
source§impl<O: ByteOrder> U32<O>
impl<O: ByteOrder> U32<O>
sourcepub const ZERO: U32<O> = _
pub const ZERO: U32<O> = _
The value zero.
This constant should be preferred to constructing a new value
using new, as new may perform an endianness swap depending
on the endianness and platform.
sourcepub const MAX_VALUE: U32<O> = _
pub const MAX_VALUE: U32<O> = _
The maximum value.
This constant should be preferred to constructing a new value using
new, as new may perform an endianness swap depending on the
endianness O and the endianness of the platform.
sourcepub fn new(n: u32) -> U32<O>
pub fn new(n: u32) -> U32<O>
Constructs a new value, possibly performing an endianness swap
to guarantee that the returned value has endianness O.
