In my a efforts to learn Rust I decided to create a strutil package containing common string functions and compare them to Go; this is not a Go vs Rust comparison, I merely decided to take a language I know well and compare it to it’s Rust counterpart code. https://github.com/rust-playground/strutil There are only a couple of functions currently but am looking to add more as I go.
I am attempting to create the most efficient and idiomatic Go & Rust code possible and would like to invite/challenge the community to contribute in making the best code possible!
Hopefully everyone can learn something new 
If you can make any of the functions more efficient, with better throughput or less allocations, … make a pull request, I’ll test and if it beats the current implementation I’ll merge and now you’re the one to beat!
