Struct mmtk::scheduler::gc_work::ScanObjects

pub struct ScanObjects<Edges: ProcessEdgesWork> {
    buffer: Vec<ObjectReference>,
    concurrent: bool,
    phantom: PhantomData<Edges>,
    bucket: WorkBucketStage,
}

Scan objects and enqueue the slots of the objects. For objects that do not support slot-enqueuing, this work packet also traces their outgoing edges directly.

This work packet does not execute policy-specific post-scanning hooks (it won’t call post_scan_object() in policy::gc_work::PolicyTraceObject). It should be used only for policies that do not perform policy-specific actions when scanning an object.

Fields

buffer: Vec<ObjectReference>

concurrent: bool

phantom: PhantomData<Edges>

bucket: WorkBucketStage

Implementations

impl<Edges: ProcessEdgesWork> ScanObjects<Edges>

pub fn new( buffer: Vec<ObjectReference>, concurrent: bool, bucket: WorkBucketStage ) -> Self

Trait Implementations

impl<E: ProcessEdgesWork> GCWork<<E as ProcessEdgesWork>::VM> for ScanObjects<E>

fn do_work(&mut self, worker: &mut GCWorker<E::VM>, mmtk: &'static MMTK<E::VM>)

Define the work for this packet. However, this is not supposed to be called directly. Usually do_work_with_stat() should be used.

fn do_work_with_stat( &mut self, worker: &mut GCWorker<VM>, mmtk: &'static MMTK<VM> )

Do work and collect statistics. This internally calls do_work(). In most cases, this should be called rather than do_work() so that MMTk can correctly collect statistics for the work packets. If the feature “work_packet_stats” is not enabled, this call simply forwards the call to do_work().

fn get_type_name(&self) -> &'static str

Get the compile-time static type name for the work packet.

impl<VM: VMBinding, E: ProcessEdgesWork<VM = VM>> ScanObjectsWork<VM> for ScanObjects<E>

type E = E

The associated ProcessEdgesWork for processing the outgoing edges of the objects in this packet.

fn get_bucket(&self) -> WorkBucketStage

Return the work bucket for this work packet and its derived work packets.

fn post_scan_object(&self, _object: ObjectReference)

Called after each object is scanned.

fn do_work_common( &self, buffer: &[ObjectReference], worker: &mut GCWorker<<Self::E as ProcessEdgesWork>::VM>, _mmtk: &'static MMTK<<Self::E as ProcessEdgesWork>::VM> )

The common code for ScanObjects and PlanScanObjects.
