Struct futures_util::io::WriteHalf[−][src]

pub struct WriteHalf<T> { /* fields omitted */ }
This is supported on crate feature io only.
Expand description

The writable half of an object returned from AsyncRead::split.

Implementations

impl<T: Unpin> WriteHalf<T>[src]

pub fn reunite(self, other: ReadHalf<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.
