I have a localization system, I compile a human-readable format into a binary one, and load each string into a hashmap depending on the selected language. Since I know each string key ahead of time, I could hash them offline, and increase performance when loading new strings.

Describe the solution you'd like

A way to insert an already hashed Key into a hashmap/hashset
