Struct mz_ore::future::DevNull

pub struct DevNull<T, E>(PhantomData<T>, PhantomData<E>);

Available on crate feature async only.

A sink that consumes its input and sends it nowhere.

Primarily useful as a base sink when folding multiple sinks into one using futures::sink::SinkExt::fanout.

Tuple Fields

0: PhantomData<T>

1: PhantomData<E>

Trait Implementations

impl<T: Debug, E: Debug> Debug for DevNull<T, E>

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

Formats the value using the given formatter.

impl<T, E> Sink<T> for DevNull<T, E>

type Error = E

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

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

Attempts to prepare the Sink to receive a value.

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

Flush any remaining output from this sink.

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

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