JIT Compiler Challenge: From Toy Calculator to Machine Code in Rust

This article presents a challenge: modify a simple Rust toy calculator to use a JIT compiler, generating and running machine code directly. Starting with a 20-line interpreter calculator, the article guides readers through the principles of JIT compilation and provides a high-level code framework. The article explains concepts like JIT and interpreters, and offers additional learning resources, such as how to generate and run machine code, and compiler resources for inspecting machine code. This is a challenging project suitable for developers with some Rust programming experience.
