Struct tokio_io::io::ReadHalf [−][src]
pub struct ReadHalf<T> { /* fields omitted */ }The readable half of an object returned from AsyncRead::split.
Implementations
impl<T: AsyncRead + AsyncWrite> ReadHalf<T>[src][−]
pub fn unsplit(self, w: WriteHalf<T>) -> T[src][−]

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