Rust and MistQL

I made a Rust port of MistQL, a query language for JSON-like data structures. I learned a lot about what goes into a program that runs a language: lexers, parsers, grammars, runtimes, and general language design. This was also my first serious project with Rust. I made a follow-up improvement that focused on memory management, which taught me a lot about Rust lifetimes, and, in particular, it taught me that JSON-like structures are very tough to represent in Rust. I’m not sure if I will get the motivation to write an in-depth post.
