Module mmtk::scheduler::worker

Structs

• GCWorker
  A GC worker. This part is privately owned by a worker thread.
• GCWorkerShared
  The struct has one instance per worker, but is shared between workers via the scheduler instance. This structure is used for communication between workers, e.g. adding designated work packets, stealing work packets from other workers, and collecting per-worker statistics.
• WorkerGroup 🔒
  A worker group to manage all the GC workers.
• WorkerShouldExit 🔒
  A special error type that indicate a worker should exit. This may happen if the VM needs to fork and asks workers to exit.

Enums

• WorkerCreationState 🔒
  Stateful part of WorkerGroup.

Constants

• STAT_BORROWED_MSG 🔒
• WORKER_ORDINAL 🔒
  Current worker’s ordinal

Functions

• current_worker_ordinal
  Get current worker ordinal. Return None if the current thread is not a worker.

Type Aliases

• PollResult 🔒
  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.
• ThreadId
  Represents the ID of a GC worker thread.
