Generic Types
Rust also supports the notion of generic types. We can write code that supports a number of types by using a stand in, often just the letter T. This includes when defining structures and enumerations.
Rust does not have higher-kinded types1. If you don't know what that means, don't worry about it. If you do, then you might be looking for them. You can stop.

In Rust 1.65.0, generic associated types were stabilized. These are sort of generic over something that is itself generic, so it's rubbing up against one aspect of higher-kinded types.
