Trait Reader 

pub trait Reader {
    // Required method
    fn read(&mut self, bytes: &mut [u8]) -> Result<(), DecodeError>;

    // Provided methods
    fn peek_read(&mut self, _: usize) -> Option<&[u8]> { ... }
    fn consume(&mut self, _: usize) { ... }
}

A reader for owned data. See the module documentation for more information.

Required Methods

fn read(&mut self, bytes: &mut [u8]) -> Result<(), DecodeError>

Fill the given bytes argument with values. Exactly the length of the given slice must be filled, or else an error must be returned.

Provided Methods

fn peek_read(&mut self, _: usize) -> Option<&[u8]>

If this reader wraps a buffer of any kind, this function lets callers access contents of the buffer without passing data through a buffer first.

fn consume(&mut self, _: usize)

If an implementation of peek_read is provided, an implementation of this function must be provided so that subsequent reads or peek-reads do not return the same bytes
