My second week of Rust (only a few hours a day though: I am on vacation after all) has me reproducing and enhancing a tool I wrote in C. It takes multiple lines and runs stats on the numbers in it.
This is useful for quick benchmarks: `for i in $(seq 10); do /usr/bin/time myprog; done | linestats`. Each line with the same literal parts is combined, with numbers replaced by "min-max(mean+/-stddev)".
The C one wasn't very clever about decimals, so it needed a good rewrite. The new code works, but needs polish, more options, optimization, tests and documentation before I release it.
The good thing about these small projects is they don't get hamstrung by Rust's glacial build times!
