Module calloop::ping

Ping to the event loop

This is an event source that just produces () events whevener the associated Ping::ping method is called. If the event source is pinged multiple times between a single dispatching, it’ll only generate one event.

This event source is a simple way of waking up the event loop from an other part of your program (and is what backs the LoopSignal). It can also be used as a building block to construct event sources whose source of event is not file descriptor, but rather an userspace source (like an other thread).
