Trait Implementations

impl<T> PartialEq for HeapBufferSource<T>

where T: TypedArrayElement,

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl<T> Traceable for HeapBufferSource<T>

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

Trace self.
