/**
* This interface is only used in order to mark the fact that

fn query_interface<T: XpCom>(&self) -> Option<RefPtr<T>>[src]
Perform a QueryInterface call on this object, attempting to dynamically cast it to the requested interface type. Returns Some(RefPtr) if the cast succeeded, and None otherwise. Read more
