Struct Listener 

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

Available on crate feature client only.

A listener for broadcasts of type T.

Constructed through Handle::on_broadcast. Dropping this removes the listener.

Implementations

impl<T> Listener<T>

pub async fn recv_raw(&mut self) -> Option<Result<RawPacket, Error>>

Receive the next raw broadcast.

Returns None if the service has been shut down.

pub async fn recv(&mut self) -> Option<Result<Packet<T>, Error>>

Receive the next broadcast.

Returns None if the service has been shut down.

pub fn clear(&mut self)

Clear the listener without dropping it.

This removes the associated listener from being notified. Any broadcasts which have already been buffered can still be received, after which Listener::recv returns None.

Trait Implementations

impl<T> Debug for Listener<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T> Drop for Listener<T>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
