Koans for the Rust programming language
Hello, I'd like to thank you for all the hard work that has gone into building this codebase. I've been telling myself for years now that I should learn rust,...
I am going through the koans, and ran into the same problem as issue #55 My googling also lead to the same solution. So here is the fix.
taking koans until arrays.rs:52 was easy, but then there are no comments explaining how to write map or filter in rust btw you could allow [discussions](https://docs.github.com/en/discussions/quickstart) in repo to address...
Usually the koans can be solved by only changing the marked line. I cannot figure out how to conditionally append a space except after the last element of the array....

Didn't want to break these out into separate tickets (although I can) but I see room for adding more koans. 1. Result 1. Option 1. Crates / Modules (requires thought...
