Public Member Functions
void	Loop ()
	Runs the main loop until Stop() is called.
void	Stop ()
	Stops the loop.
void	Step ()
	Runs one event-loop iteration: polls for I/O/timer events then resumes all coroutines whose events fired.
TPoller &	Poller ()
	Provides access to the underlying poller instance.

Detailed Description

template<typename TPoller>
class NNet::TLoop< TPoller >

Event loop that drives a poller backend.

Each call to Step() runs one polling round: it calls Poller_.Poll() to collect ready I/O events and timers, then Poller_.WakeupReadyHandles() to resume the waiting coroutines.

Loop() repeats Step() until Stop() is called. For manual control (e.g. driving the loop until a specific TFuture completes), use Step() directly:

TLoop<TDefaultPoller> loop;
TFuture<void> task = my_coroutine(loop.Poller());
while (!task.done())
    loop.Step();

For server-style programs with detached TVoidTask coroutines:

TLoop<TDefaultPoller> loop;
server(loop.Poller(), TAddress{"::", 8888});  // returns TVoidTask
loop.Loop();                                   // runs until Stop() is called

Template Parameters
