The sudoku solver I made in C, but remade in rust to get some practice using the language.
This version is more robust with a better CLI argument parser and more features.
After a few months learning more about rust, I've updated the program to be a bit more idiomatic and
robust. I've added bpaf and anyhow to make a better cli. I've also added features to add an input
and output file. They fallback to stdin/stdout respectively (allowing data to be piped in or redirected
into the program. I also added multiple printing types including simple, multiline and bordered
(previous method). simple is everything printed onto the same line, multiline is everything still
printed in a grid but without the borders around each square and bordered which prints borders around
the puzzle and every 3 x 3 area.
