Crate of the Week

This week's Crate of the Week is nom, a library of fast zero-copy parser combinators, which has already been used to create safe, high-performance parsers for a number of formats both binary and textual. nom just reached version 1.0, too, so congratulations for both the major version and the CotW status!

Thanks to Reddit user gbersac for the nom-ination! Submit your suggestions for next week!
