Trait Implementations

impl MallocSizeOf for WebGLExtensions

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.

impl Traceable for WebGLExtensions

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

Trace self.
