Struct libp2p::core::transport::memory::Chan

pub struct Chan<T = Vec<u8, Global>> { /* private fields */ }

A channel represents an established, in-memory, logical connection between two endpoints.

Implements Sink and Stream.

Trait Implementations

impl<T> Drop for Chan<T>

fn drop(&mut self)

Executes the destructor for this type.

impl<T> Sink<T> for Chan<T>

type Error = Error

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

fn poll_ready( self: Pin<&mut Chan<T>>, cx: &mut Context<'_> ) -> Poll<Result<(), <Chan<T> as Sink<T>>::Error>>

Attempts to prepare the Sink to receive a value.

fn start_send( self: Pin<&mut Chan<T>>, item: T ) -> Result<(), <Chan<T> as Sink<T>>::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 Chan<T>>, _: &mut Context<'_> ) -> Poll<Result<(), <Chan<T> as Sink<T>>::Error>>

Flush any remaining output from this sink.

fn poll_close( self: Pin<&mut Chan<T>>, _: &mut Context<'_> ) -> Poll<Result<(), <Chan<T> as Sink<T>>::Error>>

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

impl<T> Stream for Chan<T>

type Item = Result<T, Error>

Values yielded by the stream.

fn poll_next( self: Pin<&mut Chan<T>>, cx: &mut Context<'_> ) -> Poll<Option<<Chan<T> as Stream>::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.
