Type Alias mmtk::scheduler::worker::PollResult

pub(crate) type PollResult<VM> = Result<Box<dyn GCWork<VM>>, WorkerShouldExit>;

The result type of GCWorker::pool. Too many functions return Option<Box<dyn GCWork<VM>>>. In most cases, when None is returned, the caller should try getting work packets from another place. To avoid confusion, we use Err(WorkerShouldExit) to clearly indicate that the worker should exit immediately.

Aliased Type

enum PollResult<VM> {
    Ok(Box<dyn GCWork<VM>>),

}
