[−][src]Struct byteordered::ByteOrdered
Wrapper type for a reader or writer with an assumed byte order.
More details can be found at the crate level documentation.
Methods
impl<T> ByteOrdered<T, StaticEndianness<LittleEndian>>
[src]
pub fn le(inner: T) -> Self
[src]
Obtains a new reader or writer that assumes data in little endian.
pub fn endianness(&self) -> Endianness
[src]
Retrieves the runtime byte order assumed by this wrapper.
impl<T> ByteOrdered<T, StaticEndianness<BigEndian>>
[src]
pub fn be(inner: T) -> Self
[src]
Obtains a new reader or writer that assumes data in big endian.
pub fn endianness(&self) -> Endianness
[src]
Retrieves the runtime byte order assumed by this wrapper.
impl<T> ByteOrdered<T, StaticEndianness<NativeEndian>>
[src]
pub fn native(inner: T) -> Self
[src]
Obtains a new reader or writer that assumes data in the system's native endianness. While this method might sounds a bit pointless, it enables easier byte order changes through method chaining).
impl<T> ByteOrdered<T, StaticEndianness<NetworkEndian>>
[src]
impl<T> ByteOrdered<T, Endianness>
[src]
pub fn runtime(inner: T, endianness: Endianness) -> Self
[src]
Creates a new reader or writer that assumes data in the given byte order known at run-time.
Although it is equivalent to ByteOrdered::new
, this function
leaves a code signal that subsequent calls depend on conditions
resolved at run-time. If you know the data's endianness in compile
time, the other constructors are preferred (e.g. new
, le
or
be
), so as to avoid the overhead of dynamic dispatching.
pub fn endianness(&self) -> Endianness
[src]
Retrieves the runtime byte order assumed by this wrapper.
impl<T, E> ByteOrdered<T, E> where
E: Endian,
[src]
E: Endian,
pub fn new(inner: T, endianness: E) -> Self
[src]
Creates a new reader or writer that assumes data in the given byte order. This flexible constructor admits any kind of byte order (static and dynamic).
Note: The other constructors (le
, be
, native
, and
runtime
) are more recommended because they are easier to use and
leave a better signal of whether the endianness is known at compile
time or at run time. For example, if you pass a value literal of type
Endianness
(such as Endianness::Little
), the program will perform
dynamic dispatching in spite of the fixed byte order. The use of this
method is more appropriate when constructing functions which are
generic over the endianness type.
pub fn into_inner(self) -> T
[src]
Recovers the inner reader or writer from this wrapper. Information about the assumed byte order is discarded.
pub fn inner_mut(&mut self) -> &mut T
[src]
Obtains an exclusive mutable reference to the inner reader or writer in this wrapper. Information about the assumed byte order is ignored until the reference is dropped.
