Struct futures_util::io::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>

source

pub fn is_pair_of(&self, other: &WriteHalf<T>) -> bool

Checks if this ReadHalf and some WriteHalf were split from the same stream.

source§

impl<T: Unpin> ReadHalf<T>

source

pub fn reunite(self, other: WriteHalf<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.
