Expand description

A Sink part of the split pair

Implementations§

Source§

impl<S: Sink<Item> + Unpin, Item> SplitSink<S, Item>

Source

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

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 StreamExt::split.

Source§

impl<S, Item> SplitSink<S, Item>

Source

pub fn is_pair_of(&self, other: &SplitStream<S>) -> bool

Returns true if the SplitStream<S> and SplitSink<S> originate from the same call to StreamExt::split.
