Struct SignalEventHandler

pub struct SignalEventHandler<P>
where
    P: Clone + Send + 'static,
{ /* private fields */ }

Implementation of dharma::EventHandler for handling system signals synchronously. For this to work receiving of signals SIGINT and SIGTERM must be blocked in all threads in application. Otherwise non-blocking threads will catch all signals.

Implementations

impl<P> SignalEventHandler<P>

where P: Clone + Send + 'static,

pub fn new(dispatcher: DispatcherController, signaler: Signaler<P>) -> Self

SignalEventHandler constructor. Creates SignalEventHandler ready for handling SIGINT and SIGTERM signals.

Trait Implementations

impl<P> EventHandler for SignalEventHandler<P>

where P: Clone + Send + 'static,

fn get_fd(&self) -> RawFd

Returns file descriptor.

fn process_event(&mut self, _: EventKind)

Callback function executed on event received.

fn set_id(&mut self, _id: EventHandlerId)

This method is called by Dispatcher right after adding this EventHandler. Passed value is newly assigned ID of EventHandler which can be later used to delete it from Dispatcher.
