Stateful part of WorkerGroup.

Variants

Initial

Fields

local_work_queues: Vec<Worker<Box<dyn GCWork<VM>>>>

The local work queues for to-be-created workers.

The initial state. GCWorker structs have not been created and GC worker threads have not been spawn.

Spawned

All worker threads are spawn and running. GCWorker structs have been transferred to worker threads.

Surrendered

Fields

workers: Vec<Box<GCWorker<VM>>>

GCWorker instances not currently owned by active GC worker threads. Once GC workers are respawn, they will take ownership of these GCWorker instances.

Worker threads are stopping, or have already stopped, for forking. Instances of GCWorker structs are collected here to be reused when GC workers are respawn.
