I'm learning Rust, so this is just a rewrite of a simple old project into Rust.
Simply download the unscrambler binary from the latest release and run it. The interface is self-explanatory.
The main src/wordlist was pulled from words_alpha.txt by dwyl.
In order to use a different wordlist.txt, place the file inside src/ and delete the *.xz files there. Then run cargo build or cargo build --release.
