Trait Implementations

impl<VM: VMBinding> BarrierSemantics for LXRFieldBarrierSemantics<VM>

type VM = VM

fn flush(&mut self)

Flush thread-local buffers or remembered sets. Normally this is called by the slow-path implementation whenever the thread-local buffers are full. This will also be called externally by the VM, when the thread is being destroyed.

fn object_reference_write_slow( &mut self, src: ObjectReference, slot: VM::VMSlot, target: Option<ObjectReference>, )

Slow-path call for object field write operations.

fn memory_region_copy_slow( &mut self, _src: VM::VMMemorySlice, dst: VM::VMMemorySlice, )

Slow-path call for mempry slice copy operations. For example, array-copy operations.

fn load_weak_reference(&mut self, o: ObjectReference)

Loading from a weak reference field

fn object_probable_write_slow(&mut self, obj: ObjectReference)

Object will probably be modified
