Trait Implementations

impl Buffer for VecBuffer

type Error = ()

Error type emitted if failed to (re)allocate the buffer

fn new(size: usize) -> Result<Self, ()>

Allocate new buffer of at least size cap, or more.

fn enlarge(&mut self) -> Result<(), ()>

Grow appendable() part of the buffer one way or the other (by e.g. reallocating filled part of the buffer, or reallocating buffer itself)

fn len(&self) -> usize

Size of filled() part of the buffer

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

Return filled part of the buffer

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

Part of the buffer next to the filled() that can be used to append data.

fn grow(&mut self, amount: usize)

Attaches amount bytes of appendable() to filled() part of the buffer

fn consume(&mut self, amount: usize) -> &[u8]

Split filled() part of the buffer, returning up to amount bytes from the beginning while also marking them as discarded right after lifetime of returned slice ends (i.e. before another call to any of Buffer's methods that accepts &mut self).
