Struct Receiver

source
pub struct Receiver<T>(/* private fields */);
Expand description

A Relm4 receiver receives messages from a component or worker.

Implementations§

source§

impl<T> Receiver<T>

source

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

Receives a message from a component or worker.

Returns None if all senders have been disconnected.

source

pub fn recv_sync(&self) -> Option<T>

Receives a message synchronously from a component or worker.

Returns None if all senders have been disconnected.

source

pub fn into_stream(self) -> RecvStream<'static, T>

Convert this receiver into a stream that asynchronously yields messages from the channel.

source

pub async fn forward<Transformer, Output>( self, sender: impl Into<Sender<Output>>, transformer: Transformer, )
where Transformer: Fn(T) -> Output + 'static, Output: 'static,

Forwards an event from one channel to another.
