Struct tokio_io_timeout::TimeoutStream

pub struct TimeoutStream<S>(_);

A stream which applies read and write timeouts to an inner stream.

Methods

impl<S> TimeoutStream<S> where
    S: AsyncRead + AsyncWrite, 

Important traits for TimeoutStream<S>

impl<S> Read for TimeoutStream<S> where
    S: AsyncRead + AsyncWrite, impl<S> Write for TimeoutStream<S> where
    S: AsyncRead + AsyncWrite, 

pub fn new(stream: S) -> TimeoutStream<S>

Returns a new TimeoutStream wrapping the specified stream.

There is initially no read or write timeout.

pub fn read_timeout(&self) -> Option<Duration>

Returns the current read timeout.

pub fn set_read_timeout(&mut self, timeout: Option<Duration>)

Sets the read timeout.

This will reset any pending read timeout.

pub fn write_timeout(&self) -> Option<Duration>

Returns the current write timeout.

pub fn set_write_timeout(&mut self, timeout: Option<Duration>)

Sets the write timeout.

This will reset any pending write timeout.

pub fn get_ref(&self) -> &S

Returns a shared reference to the inner stream.

pub fn get_mut(&mut self) -> &mut S

Returns a mutable reference to the inner stream.

pub fn into_inner(self) -> S

Consumes the stream, returning the inner stream.

Trait Implementations

impl<S> Read for TimeoutStream<S> where
    S: AsyncRead + AsyncWrite, 

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.

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

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

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

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

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

Read the exact number of bytes required to fill buf.

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 chars(self) -> Chars<Self>

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

the semantics of a partial read/write of where errors happen is currently unclear and may change

Transforms this Read instance to an [Iterator] over [char]s.

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<S> AsyncRead for TimeoutStream<S> where
    S: AsyncRead + AsyncWrite, 

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 read_buf<B: BufMut>(&mut self, buf: &mut B) -> Poll<usize, Error>

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

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

Attempt to read from the AsyncRead into buf.

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

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.

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

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

impl<S> Write for TimeoutStream<S> where
    S: AsyncRead + AsyncWrite, 

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<(), Error>

Attempts to write an entire buffer into this write.

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

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<S> AsyncWrite for TimeoutStream<S> where
    S: AsyncRead + AsyncWrite, 

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 write_buf<B: Buf>(&mut self, buf: &mut B) -> Poll<usize, Error>

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

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.
