Hey I wrote my first somewhat-useful working #Rust language program! ?
https://github.com/datagrok/findup-rs/blob/master/src/main.rs
That Rust's standard library included almost all of the functionality made this thing trivial. It's even shorter than my shell-script version!
I'll be happier with it once I improve argument parsing and error handling. And separate the logic out from main.rs into library code. And add documentation.
