Struct websocket::stream::ReadWritePair

pub struct ReadWritePair<R, W>(pub R, pub W)
 where
    R: Read,
    W: Write;

If you would like to combine an input stream and an output stream into a single stream to talk websockets over then this is the struct for you!

This is useful if you want to use different mediums for different directions.

Trait Implementations

impl<R, W> Splittable for ReadWritePair<R, W> where     R: Read,     W: Write,

type Reader = R

The reading component of this type

type Writer = W

The writing component of this type

fn split(self) -> Result<(R, W)>

Split apart this type into a reading and writing component.

impl<R, W> Write for ReadWritePair<R, W> where     R: Read,     W: Write,

fn write(&mut self, buf: &[u8]) -> Result<usize>

Write a buffer into this object, returning how many bytes were written.

fn flush(&mut self) -> Result<()>

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.

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

Attempts to write an entire buffer into this write.

fn write_fmt(&mut self, fmt: Arguments) -> Result<()>

Writes a formatted string into this writer, returning any error encountered.

fn by_ref(&mut self) -> &mut Self

Creates a "by reference" adaptor for this instance of Write.

impl<R, W> Read for ReadWritePair<R, W> where     R: Read,     W: Write,

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

Pull some bytes from this source into the specified buffer, returning how many bytes were read.

fn read_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize>

Read all bytes until EOF in this source, placing them into buf.

fn read_to_string(&mut self, buf: &mut String) -> Result<usize>

Read all bytes until EOF in this source, appending them to buf.

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

Read the exact number of bytes required to fill buf.

unsafe fn initializer(&self) -> Initializer

🔬 This is a nightly-only experimental API. (read_initializer)

Determines if this Reader can work with buffers of uninitialized memory.

fn by_ref(&mut self) -> &mut Self

Creates a "by reference" adaptor for this instance of Read.

fn bytes(self) -> Bytes<Self>

Transforms this Read instance to an [Iterator] over its bytes.

fn chain<R>(self, next: R) -> Chain<Self, R> where     R: Read,

Creates an adaptor which will chain this stream with another.

fn take(self, limit: u64) -> Take<Self>

Creates an adaptor which will read at most limit bytes from it.

impl<R, W> AsyncRead for ReadWritePair<R, W> where     R: AsyncRead,     W: Write,

unsafe fn prepare_uninitialized_buffer(&self, buf: &mut [u8]) -> bool

Prepares an uninitialized buffer to be safe to pass to read. Returns true if the supplied buffer was zeroed out.

fn poll_read(&mut self, buf: &mut [u8]) -> Result<Async<usize>, Error>

Attempt to read from the AsyncRead into buf.

fn read_buf<B>(&mut self, buf: &mut B) -> Result<Async<usize>, Error> where     B: BufMut,

Pull some bytes from this source into the specified BufMut, returning how many bytes were read.

fn framed<T>(self, codec: T) -> Framed<Self, T> where     Self: AsyncWrite,     T: Decoder + Encoder,

Deprecated since 0.1.7

: Use tokio_codec::Decoder::framed instead

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

fn split(self) -> (ReadHalf<Self>, WriteHalf<Self>) where     Self: AsyncWrite,

Helper method for splitting this read/write object into two halves.

impl<R, W> AsyncWrite for ReadWritePair<R, W> where     W: AsyncWrite,     R: Read,

fn shutdown(&mut self) -> Poll<(), Error>

Initiates or attempts to shut down this writer, returning success when the I/O connection has completely shut down.

fn poll_write(&mut self, buf: &[u8]) -> Result<Async<usize>, Error>

Attempt to write bytes from buf into the object.

fn poll_flush(&mut self) -> Result<Async<()>, Error>

Attempt to flush the object, ensuring that any buffered data reach their destination.

fn write_buf<B>(&mut self, buf: &mut B) -> Result<Async<usize>, Error> where     B: Buf,

Write a Buf into this value, returning how many bytes were written.
