a k-mer counter in Rust using the rust-bio and rayon crates

I hope this isn’t inappropriate as a Share a Tool post, it’s more about getting feedback on and seeing if anybody here is interested in this project:

github.com/suchapalaver/krust

It’s a k-mer counter in written in Rust.

I’ve started out with bioinformatics and programming this year. This is my first program in Rust.
I’d welcome all feedback.
