Returns whether the given DOM class derives that interface.

impl ImageCacheListener for HTMLImageElement

fn generation_id(&self) -> u32

Trace self.

impl MallocSizeOf for HTMLImageElement

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.

Initializes the Reflector

impl PartialEq<HTMLImageElement> for HTMLImageElement

fn eq(&self, other: &HTMLImageElement) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
