Struct BufView

pub struct BufView<'a> { /* private fields */ }

A BufferView into a Buf.

A BufView is constructed by Buf::buffer_view, and implements BufferView, providing a view into the Buf from which it was constructed.

Trait Implementations

impl<'a> AsRef<[u8]> for BufView<'a>

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl<'a> BufferView<&'a [u8]> for BufView<'a>

fn take_front(&mut self, n: usize) -> Option<&'a [u8]>

Takes n bytes from the front of the buffer’s body.

fn take_back(&mut self, n: usize) -> Option<&'a [u8]>

Takes n bytes from the back of the buffer’s body.

fn into_rest(self) -> &'a [u8]

Converts this view into a reference to the buffer’s body.

fn len(&self) -> usize

The length of the buffer’s body.

fn is_empty(&self) -> bool

Is the buffer’s body empty?

fn take_rest_front(&mut self) -> B

Takes the rest of the buffer’s body from the front.

fn take_rest_back(&mut self) -> B

Takes the rest of the buffer’s body from the back.

fn take_byte_front(&mut self) -> Option<u8>

Takes a single byte of the buffer’s body from the front.

fn take_byte_back(&mut self) -> Option<u8>

Takes a single byte of the buffer’s body from the back.

fn peek_obj_front<T>(&mut self) -> Option<&T>

where T: FromBytes + KnownLayout + Immutable + Unaligned,

Peeks at an object at the front of the buffer’s body.

fn take_obj_front<T>(&mut self) -> Option<Ref<B, T>>

where T: KnownLayout + Immutable + Unaligned,

fn take_slice_back<T>(&mut self, n: usize) -> Option<Ref<B, [T]>>

where T: Immutable + Unaligned,

Takes a slice of objects from the back of the buffer’s body.
