Struct relm::StreamHandle [−][src]
Handle to a EventStream to emit messages.
Implementations
impl<MSG> StreamHandle<MSG>[src]
pub fn stream(&self) -> Self[src]
Same as clone(). Useful for the macro relm_observer_new.
pub fn emit(&self, msg: MSG)[src]
Send the event message to the stream and the observers.
pub fn lock(&self) -> Lock<MSG>[src]
Lock the stream (don't emit message) until the Lock goes out of scope.
pub fn observe<CALLBACK: Fn(&MSG) + 'static>(&self, callback: CALLBACK)[src]
Add an observer to the event stream. This callback will be called every time a message is emmited.
