Struct futures_util::io::ReadHalf
source · pub struct ReadHalf<T> { /* private fields */ }
Available on crate feature
io
only.Expand description
The readable half of an object returned from AsyncRead::split
.
Implementations§
source§impl<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
.

only.Wraps an
AsyncRead
in a compatibility wrapper that allows it to be
used as a futures 0.1 / tokio-io 0.1 AsyncRead
. If the wrapped type
implements AsyncWrite
as well, the result will also implement the
futures 0.1 / tokio 0.1 AsyncWrite
trait. Read more
