Struct dharma::signaler::Signaler

pub struct Signaler<P> where
    P: Clone + Send,  { /* fields omitted */ }

Signaler allows to send events (or notifications) to other parts of application possibly running in different threads. Signaler is generic over sent data type, meaning that it can convey only data of given type (therefore easiest is to choose enum).

Methods

impl<P> Signaler<P> where
    P: Clone + Send, 

fn new() -> Self

Signaler constructor.

fn subscribe(&mut self, id: SignalId, receiver: &Receiver<P>)

Subscribe given receiver for a signal id.

fn register(&mut self, receiver: &Receiver<P>)

Register receiver for control instructions like request to terminate.

fn emit(&mut self, id: SignalId, package: P)

Emit signal id containing data package. All subscribed Receivers will be notified.

fn terminate(&mut self)

Send Terminate instruction to registered Receivers indicating Signaler (possibly whole application) is going to shut down.

Trait Implementations

impl<P> Clone for Signaler<P> where
    P: Clone + Send, 

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
