This turned out to be a bit more tricky than anticipated: * We want users to see the type this crate exposes, so we need to wrap it all. * We don't want to deal with validating labels here, so we need to delegate. * We need it to be thread-safe, so that we can generate globals. But we also don't want users to deal with locking. * We want a nice-ish API. This now achieves all of this with just one little trick: a sealed trait. That way we can easily extend it to more types, without adding much more code. Note: It might have been nice to use the index operator (`[]`), but that's defined by a trait in Rust and returns a reference to existing data. We thus can't use it and instead provide a simple `get()` method. Differential Revision: https://phabricator.services.mozilla.com/D72805
