Struct bee_runtime::event::Bus

pub struct Bus<'a, ID = TypeId> { /* private fields */ }

An event bus for arbitrary event types.

Implementations

impl<'a, ID: Clone + PartialEq> Bus<'a, ID>

pub fn dispatch<E: Any>(&self, event: E)

Dispatch an event via this event bus.

All active listeners registered for this event will be invoked.

pub fn add_listener_raw<E: Any, F: Fn(&E) + Send + Sync + 'a>(
    &self,
    id: ID,
    handler: F
)

Add an event listener bound to a specific event type, E, and registered with the given ID.

pub fn remove_listeners_by_id(&self, id: ID)

Remove all event listeners registered with the given ID, dropping them in the process.

impl<'a> Bus<'a, TypeId>

pub fn add_listener<T: Any, E: Any, F: Fn(&E) + Send + Sync + 'a>(
    &self,
    handler: F
)

Add an event listener bound to a specific event type, E, and bound to a type T.

This event listener will be removed when Bus::remove_listeners_by_id is called with the TypeId of T.

pub fn add_static_listener<E: Any, F: Fn(&E) + Send + Sync + 'a>(
    &self,
    handler: F
)

Add an event listener bound to a specific event type, E, registered using a hidden type that will prevent its removal until the event bus is dropped.

Trait Implementations

fn default() -> Self
