Struct SFTTrace 

pub struct SFTTrace<VM: VMBinding> {
    phantom_data: PhantomData<VM>,
}

A Trace implementation that dispatches the trace_object method through crate::policy::sft::SFT::sft_trace_object using the Space Function Table (SFT).

Because SFT methods cannot be general, SFTTrace cannot be used for plans that needs multiple traces. It is sufficient for simple plans such as MarkSweep and SemiSpace.

Fields

phantom_data: PhantomData<VM>

Trait Implementations

impl<VM: VMBinding> Clone for SFTTrace<VM>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<VM: Default + VMBinding> Default for SFTTrace<VM>

fn default() -> SFTTrace<VM>

Returns the “default value” for a type.

impl<VM: VMBinding> Trace for SFTTrace<VM>

type VM = VM

The VM binding type this type serves.

fn from_mmtk(_mmtk: &'static MMTK<Self::VM>) -> Self

Instantiate from an MMTK instance.

fn trace_object<Q: ObjectQueue>( &self, worker: &mut GCWorker<VM>, object: ObjectReference, queue: &mut Q, ) -> ObjectReference

Trace the object. More precisely, it visits an object graph edge that points to object.

fn post_scan_object(&self, _object: ObjectReference)

The post-scan hook to be call after scanning object.

fn may_move_objects() -> bool

Return true if Self::trace_object may move any object. If any space of the current plan may move objects during this trace, this method should return true.
