Struct tokio_codec::FramedWrite

pub struct FramedWrite<T, E> { /* private fields */ }

A Sink of frames encoded to an AsyncWrite.

Implementations

impl<T, E> FramedWrite<T, E>

where T: AsyncWrite, E: Encoder,

pub fn new(inner: T, encoder: E) -> FramedWrite<T, E>

Creates a new FramedWrite with the given encoder.

impl<T, E> FramedWrite<T, E>

pub fn get_ref(&self) -> &T

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

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

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

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) -> T

Consumes the FramedWrite, 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 encoder(&self) -> &E

Returns a reference to the underlying decoder.

pub fn encoder_mut(&mut self) -> &mut E

Returns a mutable reference to the underlying decoder.

Trait Implementations

impl<T, U> Debug for FramedWrite<T, U>

where T: Debug, U: Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T, I, E> Sink<I> for FramedWrite<T, E>

where T: AsyncWrite + Unpin, E: Encoder<Item = I> + Unpin, E::Error: From<Error>,

type Error = <E as Encoder>::Error

The type of value produced by the sink when an error occurs.

fn poll_ready( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Result<(), Self::Error>>

Attempts to prepare the Sink to receive a value.

fn start_send(self: Pin<&mut Self>, item: I) -> Result<(), Self::Error>

Begin the process of sending a value to the sink. Each call to this function must be preceded by a successful call to poll_ready which returned Poll::Ready(Ok(())).

fn poll_flush( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Result<(), Self::Error>>

Flush any remaining output from this sink.

fn poll_close( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Result<(), Self::Error>>

Flush any remaining output and close this sink, if necessary.

impl<T, D> Stream for FramedWrite<T, D>

where T: Stream + Unpin, D: Unpin,

type Item = <T as Stream>::Item

Values yielded by the stream.

fn poll_next( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Option<Self::Item>>

Attempt to pull out the next value of this stream, registering the current task for wakeup if the value is not yet available, and returning None if the stream is exhausted.

fn size_hint(&self) -> (usize, Option<usize>)

Returns the bounds on the remaining length of the stream.
