Required methods

fn read_map<R, F>(&mut self, n: usize, f: F) -> Result<R, Self::Error> where
    F: FnOnce(Bytes<'a, '_>) -> R, 

Reads exactly n bytes and passes them to the given function

An error must be returned if there are fewer than n bytes left.

Provided methods

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

Reads exactly buf.len() bytes and writes them to the supplied buffer

An error must be returned if there are fewer than buf.len() bytes left.
