Struct DefaultObjectTracerContext 

pub(crate) struct DefaultObjectTracerContext<T: Trace> {
    stage: WorkBucketStage,
    phantom_data: PhantomData<T>,
}

This implementation of ObjectTracerContext creates the DefaultObjectTracer to expand the transitive closure during a stop-the-world tracing GC or the final mark pause of a concurrent GC. It is used during object scanning as well as weak reference processing.

Fields

stage: WorkBucketStage

phantom_data: PhantomData<T>

Implementations

impl<T: Trace> DefaultObjectTracerContext<T>

pub fn new(stage: WorkBucketStage) -> Self

Trait Implementations

impl<T: Clone + Trace> Clone for DefaultObjectTracerContext<T>

fn clone(&self) -> DefaultObjectTracerContext<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Trace> ObjectTracerContext<<T as Trace>::VM> for DefaultObjectTracerContext<T>

type TracerType<'w> = DefaultObjectTracer<'w, T>

The concrete ObjectTracer type.

fn with_tracer<'w, R, F>(&self, worker: &'w mut GCWorker<T::VM>, func: F) -> R

where F: FnOnce(&mut Self::TracerType<'w>) -> R,

Create a temporary ObjectTracer and provide access in the scope of func.
