Struct tokio::io::ReadHalf

source · [−]

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

This is supported on crate feature io-util only.

Expand description

The readable half of a value returned from 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

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

Reunites with a previously split WriteHalf.

Panics

If this ReadHalf and the given WriteHalf do not originate from the same split operation this method will panic. This can be checked ahead of time by comparing the stream ID of the two halves.
