Hi all,

I’m experimenting with Rust and wanted to ask if anyone here has experience building small word-based tools. Specifically, I’m looking into making a Wordfeud UK helper (something like a word validator or move suggestion engine).

The idea is to load the UK dictionary and then efficiently generate valid word combinations from a given rack of letters. I’ve seen approaches in Python using tries or DAWGs, but I’d like to explore how to implement this efficiently in Rust for performance.

• What data structure would you recommend for fast lookups in Rust?
• Is there a crate that already handles Scrabble/Wordfeud-style dictionaries?
• Any advice on handling large word lists in memory without major performance issues?

Thanks in advance!
