Rust generic associated types are explained on the Rust blog: https://blog.rust-lang.org/2021/08/03/GATs-stabilization-push.html https://blog.rust-lang.org/2021/08/03/GATs-stabilization-pus... GATs (generic associated types) allow you to define type, lifetime, or const generics on associated types. If you're familiar with languages that have "higher-kinded types", then you could call GATs type constructors on traits.
