[][src]Struct tokio_util::codec::Framed

pub struct Framed<T, U> { /* fields omitted */ }

A unified Stream and Sink interface to an underlying I/O object, using the Encoder and Decoder traits to encode and decode frames.

You can create a Framed instance by using the AsyncRead::framed adapter.

Methods

impl<T, U> Framed<T, U> where
    T: AsyncRead + AsyncWrite,
    U: Decoder + Encoder
[src]

pub fn new(inner: T, codec: U) -> Framed<T, U>[src]

Provides a Stream and Sink interface for reading and writing to this Io object, using Decode and Encode to read and write the raw data.

Raw I/O objects work with byte sequences, but higher-level code usually wants to batch these into meaningful chunks, called "frames". This method layers framing on top of an I/O object, by using the Codec traits to handle encoding and decoding of messages frames. Note that the incoming and outgoing frame types may be distinct.

This function returns a single object that is both Stream and Sink; grouping this into a single object is often useful for layering things like gzip or TLS, which require both read and write access to the underlying object.

If you want to work more directly with the streams and sink, consider calling split on the Framed returned by this method, which will break them into separate objects, allowing them to interact more easily.

impl<T, U> Framed<T, U>[src]

pub fn from_parts(parts: FramedParts<T, U>) -> Framed<T, U>[src]

This objects takes a stream and a readbuffer and a writebuffer. These field can be obtained from an existing Framed with the into_parts method.

pub fn get_ref(&self) -> &T[src]

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

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 get_mut(&mut self) -> &mut T[src]

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

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 codec(&self) -> &U[src]

Returns a reference to the underlying codec wrapped by Frame.

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

pub fn codec_mut(&mut self) -> &mut U[src]

Returns a mutable reference to the underlying codec wrapped by Frame.

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

pub fn read_buffer(&self) -> &BytesMut[src]

Returns a reference to the read buffer.

pub fn into_inner(self) -> T[src]

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

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_parts(self) -> FramedParts<T, U>[src]

Consumes the Frame, returning its underlying I/O stream, the buffer with unprocessed data, and the codec.

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.
