Trait rquickjs_core::class::Trace

pub trait Trace<'js> {
    // Required method
    fn trace<'a>(&self, tracer: Tracer<'a, 'js>);
}

A trait for classes for tracing references to quickjs objects.

Quickjs uses reference counting with tracing to break cycles. As a result implementing this trait incorrectly by not tracing an object cannot result in unsound code. It will however result in memory leaks as the GC will be unable to break cycles which in turn result in cyclic references being kept alive forever.
