Struct EventBus 

pub struct EventBus { /* private fields */ }

Cloneable handle to the in-process bus. Cloning shares the same channels.

Implementations

impl EventBus

pub fn new() -> Self

pub fn publish<E: Event>(&self, event: E) -> Result<usize, PublishError>

Publish an event. Returns the number of live subscribers that received it.

Publishing with no subscribers is not an error — a connector must not care whether anyone is listening.

pub fn subscribe<E: Event>(&self) -> Result<EventStream<E>, PublishError>

Subscribe to every future event of type E.

Events published before subscribing are not replayed.
