Trait script::dom::bindings::root::StableTraceObject

pub unsafe trait StableTraceObject {

    fn stable_trace_object(&self) -> *const dyn JSTraceable;
}
Expand description

StableTraceObject represents values that can be rooted through a stable address that will not change for their whole lifetime. It is an unsafe trait that requires implementors to ensure certain safety guarantees.

§Safety

Implementors of this trait must ensure that the trace method correctly accounts for all owned and referenced objects, so that the garbage collector can accurately determine which objects are still in use. Failing to adhere to this contract may result in undefined behavior, such as use-after-free errors.

Required Methods§

source

fn stable_trace_object(&self) -> *const dyn JSTraceable

Returns a stable trace object which address won’t change for the whole lifetime of the value.
