PauseRequestOutcome

mmtk::global_state

Enum PauseRequestOutcome 

Source 
pub(crate) enum PauseRequestOutcome {
    Uninitialized,
    AlreadyRequested,
    Requested,
}
Expand description

The outcome of GcStatusWord::try_request_pause.

Variants§

§

Uninitialized

MMTk has not been initialized yet (initialize_collection() has not been called), so there are no GC worker threads to run a collection; no pause was (or could be) requested.

§

AlreadyRequested

A pause was already requested (by this call or a racing one); the caller does not need to do anything further.

§

Requested

This call transitioned the status to PauseRequested; the caller is responsible for requesting the pause (e.g. notifying the scheduler) exactly once.

where T: Any,

§

fn into_any(self: Box<T>) -> Box<dyn Any>

Converts Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>, which can then be downcast into Box<dyn ConcreteType> where ConcreteType implements Trait.
