Module worker 

GC worker threads: the worker::GCWorker struct representing a single worker, the (crate-private) WorkerGroup that manages all workers, and per-worker shared state.

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.
