Trait Implementations

impl JSTraceable for WeakRangeVec

unsafe fn trace(&self, _: *mut JSTracer)

Trace self.

impl MallocSizeOf for WeakRangeVec

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.
