10/// A trait for dealing with type-safe indices into associative data structures
11/// like [`Map`]s.
12///
13/// Through the use of this trait, we get compile time checks that we are not
14/// using the wrong type of index into our data structures.
15///
16/// It acts as a thin wrapper over `usize` and in most usage patterns has no
17/// runtime overhead.
