Struct local_channel::mpsc::Receiver

source ·
pub struct Receiver<T> { /* private fields */ }
Expand description

The receiving end of a channel which implements the Stream trait.

This is created by the channel function.

Implementations§

source§

impl<T> Receiver<T>

source

pub async fn recv(&mut self) -> Option<T>

Receive the next value.

Returns None if the channel is empty and has been closed explicitly or when all senders have been dropped and, therefore, no more values can ever be sent though this channel.

source

pub fn sender(&self) -> Sender<T>

Create an associated Sender.
