Traits

ObjectTracer

Callback trait of scanning functions that directly trace through object graph edges.

ObjectTracerContext

An ObjectTracerContext gives a GC worker temporary access to an ObjectTracer, allowing the GC worker to trace objects. This trait is intended to abstract out the implementation details of tracing objects, enqueuing objects, and creating work packets that expand the transitive closure, allowing the VM binding to focus on VM-specific parts.

RootsWorkFactory

Root-scanning methods use this trait to create work packets for processing roots.

Scanning

VM-specific methods for scanning roots/objects.

SlotVisitor

Callback trait of scanning functions that report slots.
