str_id

Interns str slices into ID values

lib.rs:

Interns str slices, giving you back an ID value.

The ID value is a newtyped [NonZeroUsize]. You get approximately the same benefits as using Box<Str>, but when the same str is used in multiple locations they'll resolve to the same ID value.

All str slice data resides in a global cache. There is no way to purge the cache once a str slice has been interned. This library is not intended for long running programs.
