Menhir and Friends: the State of the Art of Parsing in Rust by Naomi Testard In this talk we present Menhir, a very powerful LR parsers generator, and how to use it to write Rust parsers (and lexers). We also show some details of the internals of Menhir’s backend for Rust, as well as a short comparative survey of other similar parsing tools and techniques for Rust out here.
