Struct tokio::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: AsyncRead + AsyncWrite,

source

pub fn unsplit(self, r: ReadHalf<T>) -> T

Reunite with a previously split ReadHalf.

panics

If this WriteHalf and the given ReadHalf do not originate from the same AsyncRead::split operation this method will panic.
