A crafting interpreter of programming language Jialox implemented in rust, which is based on book "CRAFTING INTERPRETERS" and authored by Jiashu.
I started learning this book from Uncle Scientist, a youtuber who has released many practical Rust tutorials. Welcome to subscribe to his channel. This series of videos teaches this book.

This project is divided into different release versions based on chapter learning, for example, Section 4 corresponds to version 0.1.0, Section 5 corresponds to version 0.2.0, and so on. Alternatively, you can directly refer to the Release branches to find the desired version.
You can start learning from version 0.1.0, gradually improve from a small project, and finally complete the entire interpreter. It is really impressive!
