Struct websocket_base::stream::async::ReadHalf

source · [−]

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

Expand description

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

Implementations

source

impl<T> ReadHalf<T> where
T: AsyncRead + AsyncWrite,

source

pub fn unsplit(self, w: WriteHalf<T>) -> T

Reunite with a previously split WriteHalf.

Panics

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