Struct DequeBuffer 

pub struct DequeBuffer { /* private fields */ }

Growable byte buffer that supports efficient front-extension.

Implementations

impl DequeBuffer

pub fn with_capacity(back: usize, front: usize) -> Self

Create with reserved space for back bytes in the back and front in the front.

pub fn clear(&mut self)

Reset the buffer to empty (but keep allocation).

pub fn extend_front(&mut self, slice: &[u8])

Prepend slice to the front.

pub fn len(&self) -> usize

Number of bytes in the buffer.

pub fn is_empty(&self) -> bool

True if empty.

Trait Implementations

impl AsMut<[u8]> for DequeBuffer

fn as_mut(&mut self) -> &mut [u8]

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

impl AsRef<[u8]> for DequeBuffer

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

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

impl Clone for DequeBuffer

fn clone(&self) -> DequeBuffer

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DequeBuffer

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> Extend<&'a u8> for DequeBuffer
