Composable event loops combine the cheap synchronicity of event loops with the composability of preempted threads.
Two modular event queue classes are provided:
- EventLoop - for loops coupled with a c++ managed thread
- EventQueue - for manually managed event queues
The Event class takes advantage of the extensibility of FuncPtr to allow an event to be passed through APIs as a normal function.
More information on composable event loops.
