stable_deref_trait This crate defines an unsafe marker trait, StableDeref, for container types which deref to a fixed address which is valid even when the containing type is moved. For example, Box, Vec, Rc, Arc and String implement this trait. Additionally, it defines CloneStableDeref for types like Rc where clones deref to the same address. 6
