GraphObserveAllReactive

Struct GraphObserveAllReactive 

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

Reactive variant of GraphObserveAll that auto-subscribes late-added named nodes via Graph namespace-change notifications.

Drop to unsubscribe everything.

Implementations§

Source§

impl GraphObserveAllReactive

Source

pub fn subscribe<F>(&mut self, sink: F) -> usize
where F: Fn(&str, &[Message]) + Send + Sync + 'static,

Subscribe a sink to all current AND future named nodes.

The sink receives (name, &[Message]) tuples, same as GraphObserveAll::subscribe. Returns the number of nodes subscribed at call time (future auto-subscriptions are not counted).

§Panics

Panics if called more than once on the same handle. The v1 contract is “single-shot wiring”; rebuild the handle via Graph::observe_all_reactive to install another sink.
