Struct futures::io::ReadHalf [−][src]
pub struct ReadHalf<T> { /* fields omitted */ }
Expand description
The readable half of an object returned from AsyncRead::split
.
Implementations
impl<T> ReadHalf<T> where
T: Unpin,
[src]
impl<T> ReadHalf<T> where
T: Unpin,
[src]pub fn reunite(self, other: WriteHalf<T>) -> Result<T, ReuniteError<T>>
[src]
pub fn reunite(self, other: WriteHalf<T>) -> Result<T, ReuniteError<T>>
[src]Attempts to put the two “halves” of a split AsyncRead + AsyncWrite
back
together. Succeeds only if the ReadHalf<T>
and WriteHalf<T>
are
a matching pair originating from the same call to AsyncReadExt::split
.
