Methods

impl SignalerAsync

pub fn new() -> SignalerAsync

pub fn subscribe(     &self,     signal: &str,     f: Box<Fn(Signal) + Send + 'static> ) -> Result<u32, Error>

subscribe a callback to a signal This callback will be called with all signals that starts with the signal string, for example, if you subscribe a callback to the signal "custom-signal", this callback will have the following behaviour:

signal | f is called -------------------------------+------------- "custom-signal" | true "custom-signal2" | true "custom-signal-with more text" | true "custom" | false "custom-signa" | false "other signal" | false

This method returns the callback id that can be used to unsubscribe

pub fn unsubscribe(&self, id: u32)

Unsubscribe a callback by id. Use the id returned in the subscribe method to remove this signal

pub fn clear_signal(&self, signal: &str)

pub fn signal_loop(&self)
