Struct futures_util::io::ReadHalf
source · [−]pub struct ReadHalf<T> { /* private fields */ }Expand description
The readable half of an object returned from AsyncRead::split.
Implementations
sourceimpl<T: Unpin> ReadHalf<T>
impl<T: Unpin> ReadHalf<T>
sourcepub fn reunite(self, other: WriteHalf<T>) -> Result<T, ReuniteError<T>>
pub fn reunite(self, other: WriteHalf<T>) -> Result<T, ReuniteError<T>>
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.
