Implementations§

Source§

impl<S> SplitSink<S>
where S: Sink,

Source

pub fn reunite(self, other: SplitStream<S>) -> Result<S, ReuniteError<S>>

Attempts to put the two “halves” of a split Stream + Sink back together. Succeeds only if the SplitStream<S> and SplitSink<S> are a matching pair originating from the same call to Stream::split.
