Build my first useful Rust tool.

https://github.com/nevakrien/RustSearch

this was surprisingly easy to get right and it works RIDICULOUSLY fast. searching my entire desktop including runing through at least 2 ML datasets takes like... 5 seconds.
and it took me basically 0 effort to get working.

it feels a lot more like python than it does C. just a nice dev experience with good error messages and no UB non sense to debug.

still very new to this more functional style of programing. just a lot more features and functions to use than C. I think it would do me good to learn it tho. I want to have a better range.
