Expand description

Rooted<T> with a T that uses the Traceable RootKind uses dynamic dispatch on the C++ side for custom tracing. This trait provides trace logic via a vtable when creating a Rust instance of the object.

Provided Associated Constants§

const VTABLE: RootedVFTable = _

Required Methods§

source

unsafe fn do_trace(&mut self, trc: *mut JSTracer)

Used by TraceableTrace implementer to trace its contents. Corresponds to virtual trace call in a Rooted that inherits from StackRootedTraceableBase (C++).
