Required Methods

fn reserve(&mut self, size: usize) -> Result<(), Self::Error>

fn extend_from_slice_in_capacity( &mut self, data: &[u8], ) -> Result<(), Self::Error>

Implementations on Foreign Types

impl WriterBackend for Vec<u8>

io::Write generates bloated code (with backtrace for every byte written), so small boxes are written infallibly.

type Error = OOM
