EventSource

bb_runtime::framework::event_source

Struct EventSource 

Source 
pub struct EventSource { /* private fields */ }
Expand description

event_kind → Vec<ComponentTag> subscription table.

Implementations§

Source§

impl EventSource

Source

pub fn new() -> Self

Construct a fresh, empty registry.

Source

pub fn subscribe(&mut self, event_kind: &str, tag: ComponentTag)

Subscribe tag to events of event_kind. Idempotent - re-subscribing the same tag is a no-op.

Source

pub fn unsubscribe(&mut self, event_kind: &str, tag: ComponentTag)

Remove tag’s subscription to event_kind if present.

Source

pub fn subscribers(&self, event_kind: &str) -> &[ComponentTag]

Subscribers to event_kind. Returns an empty slice when no component is subscribed.

Source

pub fn len(&self) -> usize

Number of distinct event kinds with at least one subscriber.

Source

pub fn is_empty(&self) -> bool

true when no subscriptions are registered.
