krish's blog • Parsing JSON in 500 lines of Rust

Last semester at university, I took a course called "Syntax-Based Tools and Compilers". It focused on building a scanner, parser, compiler, and so on for a language called PL0. We used Python in the course, but I was really interested in learning Rust at the time. So, I decided to embark on a side project (yes, another one!). This time, I wanted to build a JSON parser in Rust. My goal was to test

500行で? Rustの文字列→数値変換ってJSONと100%互換性ある? と思いながら読んだら、案の定適当に実装していると書かれていて、このパーサーはまともなJSON処理系としては使えないな、ってなった。数値文字列変換は難しいぞ
