Stage 8.12: Generic Functions

Generics in Rust work hand in hand with traits. When we describe a parameterized type T we can constrain what types can be used as an argument by listing what required traits the argument must implement.

In this example type T must implement trait Foo:

fn my_function<T>(foo: T)
where
    T: Foo
{
    ...
}

By using generics we create static typed functions at compile time that will have known types and sizes, allowing us to perform static dispatch and store as a sized value.
