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 is_thread_blocked_on_host(&self, thread: &Thread<'tcx>) -> bool

Check whether the provided thread is currently blocked on host I/O. This means, it’s either blocked on an I/O operation directly or it’s blocked on an epoll instance which contains a host source interest.

fn unblock_expired_deadlines(&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 deadline. If all ready threads have no deadline set, None is returned.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
