ShutdownFanout

micromegas::servers::shutdown

Struct ShutdownFanout 

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

Fans a shutdown future out to N consumers via a watch channel.

subscribe() returns a future that completes once the original shutdown future has fired — usable as the drain trigger for axum/tonic and as the deadline arm. Subscribers created after the signal has fired complete immediately.

Implementations§

where F: Future<Output = ()> + Send + 'static,

Source

pub fn subscribe(&self) -> impl Future<Output = ()> + Send + 'static
