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.</p>
<p>It is intended to be used by crates such as <a href="https://crates.io/crates/owning_ref">owning_ref</a> and <a href="https://crates.io/crates/rental">rental</a>, as well as library authors who wish to make their code interoperable with such crates. For example, if you write a custom Vec type, you can implement StableDeref, and then users will be able to use your custom type together with owning_ref and rental.</p>
<p>no_std support can be enabled by disabling default features (specifically &quot;std&quot;). In this case, the trait will not be implemented for the std types mentioned above, but you can still use it for your own types.</p>
