Trait Implementations

impl<T: Debug> Debug for Drain<T>

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

Formats the value using the given formatter.

impl<T> Sink<T> for Drain<T>

type SinkError = DrainError

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::SinkError>>

Attempts to prepare the Sink to receive a value.

fn start_send(self: Pin<&mut Self>, _item: T) -> Result<(), Self::SinkError>

Begin the process of sending a value to the sink. Each call to this function must be proceeded 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::SinkError>>

Flush any remaining output from this sink.

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

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