Struct Accessor 

pub struct Accessor<B, T> { /* private fields */ }

A tool for converting zerocopy’s Ref<_, T>s into &T/&mut T based on need and input B mutability.

This primarily reduces pointer sizes for fixed-width packet parts as an internal component of all Valid packets.

Zerocopy issue #368 would obviate the need for this, but I do not believe it is under active development. It would also open us back up to allowing any B rather than simply those which are IntoByteSlice.

Implementations

impl<B: SplitByteSlice, T: FromBytes + IntoBytes + KnownLayout + Immutable> Accessor<B, T>

pub fn read_from_prefix<'a>(buf: B) -> Result<(Self, B), ParseError>

where B: 'a + IntoBufPointer<'a>, T: 'a,

Parses out a fixed-width packet chunk T from the start of a given buffer.

Trait Implementations

impl<B: ByteSlice, T: FromBytes + KnownLayout + Immutable> Deref for Accessor<B, T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<B: ByteSliceMut, T: FromBytes + KnownLayout + Immutable> DerefMut for Accessor<B, T>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.
