pub struct Isize<O>(/* private fields */);
Expand description
A word-sized signed integer stored in a given byte order.
Isize
is like the native isize
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
.
An Isize
can be constructed using
the new
method, and its contained value can be obtained as a native
isize
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 Isize
has endianness O
and that, b) the layout of isize
has
the platform’s native endianness.
Isize
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§
Source§impl<O> Isize<O>
impl<O> Isize<O>
Sourcepub const ZERO: Isize<O>
pub const ZERO: Isize<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 fn from_bytes(bytes: [u8; 8]) -> Isize<O>
pub const fn from_bytes(bytes: [u8; 8]) -> Isize<O>
Constructs a new value from bytes which are already in O
byte
order.
Source§impl<O: ByteOrder> Isize<O>
impl<O: ByteOrder> Isize<O>
Sourcepub const fn new(n: isize) -> Isize<O>
pub const fn new(n: isize) -> Isize<O>
Constructs a new value, possibly performing an endianness
swap to guarantee that the returned value has endianness
O
.
