Struct DefaultRootsWorkFactory 

pub(crate) struct DefaultRootsWorkFactory<VM: VMBinding, DT: Trace<VM = VM>, PT: Trace<VM = VM>> {
    pub(crate) mmtk: &'static MMTK<VM>,
    phantom: PhantomData<(DT, PT)>,
}

An implementation of RootsWorkFactory for stop-the-world tracing GC. It will create work packets to find the transitive closure from roots, assuming mutators are stopped during the GC.

It creates the ProcessSlots work packet to handle non-pinning roots, and ProcessPinningRoots to handle pinning roots (transitive or not). The work packets will be added to the WorkBucketStage::TPinningClosure, WorkBucketStage::PinningRootsTrace and WorkBucketStage::Closure buckets depending on the kinds of roots.

DT and PT are the Trace types for the default trace and pinning trace, respectively.

Fields

mmtk: &'static MMTK<VM>

phantom: PhantomData<(DT, PT)>

Trait Implementations

impl<VM: VMBinding, DT: Trace<VM = VM>, PT: Trace<VM = VM>> Clone for DefaultRootsWorkFactory<VM, DT, PT>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<VM: VMBinding, DT: Trace<VM = VM>, PT: Trace<VM = VM>> RootsWorkFactory<<VM as VMBinding>::VMSlot> for DefaultRootsWorkFactory<VM, DT, PT>

fn create_process_roots_work(&mut self, slots: Vec<VM::VMSlot>)

Create work packets to handle non-pinned roots. The roots are represented as slots so that they can be updated.

fn create_process_pinning_roots_work(&mut self, nodes: Vec<ObjectReference>)

Create work packets to handle non-transitively pinning roots.

fn create_process_tpinning_roots_work(&mut self, nodes: Vec<ObjectReference>)

Create work packets to handle transitively pinning (TP) roots.
