Provided Methods

fn run_on_stack_empty(&mut self) -> InterpResult<'tcx, Poll<()>>

fn schedule(&mut self) -> InterpResult<'tcx, SchedulingAction>

Decide which action to take next and on which thread.

The currently implemented scheduling policy is the one that is commonly used in stateless model checkers such as Loom: run the active thread as long as we can and switch only when we have to (the active thread was blocked, terminated, or has explicitly asked to be preempted).

If GenMC mode is active, the scheduling is instead handled by GenMC.

fn poll_and_unblock(&mut self, timeout: Option<Duration>) -> InterpResult<'tcx>

Poll for I/O events until either an I/O event happened or the timeout expired. The different timeout values are described in BlockingIoManager::poll.

fn unblock_expired_timeouts(&mut self) -> InterpResult<'tcx, Option<Duration>>

Find all threads with expired timeouts, unblock them and execute their timeout callbacks.

This method returns the minimum duration until the next thread timeout expires. If all ready threads have no timeout set, None is returned.
