Crusted Interpreter: The Whole Typed Affair

David Beazley — Jan 7, 2026 — tutorial

Why watch

A complete live-coding implementation of the bytecode virtual machine portion of Robert Nystrom's Crafting Interpreters book, building the Lox programming language from scratch in Rust. The creator follows the book chapter-by-chapter for the first time while implementing a stack-based VM with opcodes, constants, variables, and function calls. Ideal for developers interested in language implementation, compilers, and virtual machines who want to see a complete interpreter build from the ground up.
