Struct futures::io::WriteHalf

source · [−]

pub struct WriteHalf<T> { /* private fields */ }

Expand description

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

Implementations

source

impl<T> WriteHalf<T> where
T: Unpin,

source

pub fn reunite(self, other: ReadHalf<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.
