Chromium recommends to use flat_map, a map-like interface based on a sorted array, for data structures facing GUI or similar when the number of items in the map is naturally bounded. It is faster and more compact compared with hash maps.
A looong time ago I wrote my first blog post - on a now defunct website - about a VecMap where I did exactly that. Sort when needed and full flat array. That said flat_map as coined by Google is an acronym for swiss tables. See [1]. I.e. exactly what Rust's standard library `HashMap` is, also the one being tested here.
