pub struct SubscriptionHandle { /* private fields */ }Expand description
Opaque handle for an active subscription. Drop to unsubscribe.
Implementations§
Source§impl SubscriptionHandle
impl SubscriptionHandle
Sourcepub async fn recv(&mut self) -> Option<(EventTopic, EventPayload)>
pub async fn recv(&mut self) -> Option<(EventTopic, EventPayload)>
Receive the next event. Returns None when the bus is closed.
Source§impl SubscriptionHandle
impl SubscriptionHandle
Sourcepub fn from_receiver(rx: Receiver<(EventTopic, EventPayload)>) -> Self
pub fn from_receiver(rx: Receiver<(EventTopic, EventPayload)>) -> Self
Construct a subscription from an mpsc receiver. Used by port impls
(e.g. oxicode_fs::InProcessEventBus) — not part of the public SDK API
for end-users.

Convert
&mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &mut Any’s vtable from &mut Trait’s.
