Struct ReadFramed

pub struct ReadFramed<T, C>(/* private fields */);

A Stream interface to ReadBuf object

Implementations

impl<T, C> ReadFramed<T, C>

pub fn get_ref(&self) -> &ReadBuf<T>

Returns a reference to the underlying I/O stream wrapped by ReadFramed.

pub fn get_mut(&mut self) -> &mut ReadBuf<T>

Returns a mutable reference to the underlying I/O stream wrapped by ReadFramed.

Note that care should be taken to not tamper with the underlying stream of data coming in as it may corrupt the stream of frames otherwise being worked with.

pub fn into_inner(self) -> ReadBuf<T>

Consumes the ReadFramed, returning its underlying I/O stream.

Note that stream may contain both input and output data buffered.
