Hand-rolled JSON Parser in Rust: A 800-line Side Project

Inspired by a university compilers course, the author built a JSON parser in Rust as a side project. The article details the design and implementation, covering handling various JSON data types (strings, numbers, arrays, objects), error handling, and performance testing. The final parser clocks in at around 800 lines, including improved error messages for easier debugging. Performance tests, though not optimized, showed decent parsing speeds.
