Trait for writable buffer.

Required methods

fn len(&self) -> usize

Returns position/offset for data to be written at.

fn is_empty(&self) -> bool

Returns true if buffer contains no data.

fn reserve(&mut self, additional: usize) -> Result<(), ()>

Reserves specified number of bytes in the buffer.

fn resize(&mut self, new_len: usize, value: u8)
