Implementations

impl Buffer

pub fn new(max_length: usize) -> Self

Constructs a new, empty Buffer.

pub fn len(&self) -> usize

Returns the number of elements in the buffer.

pub fn resize(&mut self, new_size: usize)

Resizes the buffer in-place so that len is equal to new_size.

pub fn extend_from_slice(&mut self, bytes: &[u8])

Appends all elements in a slice to the buffer.

pub fn advance(&mut self, cnt: usize)

Shortens the buffer, dropping the first cnt bytes and keeping the rest.

pub fn is_empty(&self) -> bool

Returns true if the buffer contains no elements.

Trait Implementations

impl AsMut<[u8]> for Buffer

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

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

impl AsRef<[u8]> for Buffer

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

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

impl Debug for Buffer

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

Formats the value using the given formatter.
