The author benchmarks different VM dispatch styles in Rust, including tail-call interpretation and a stack machine variant, comparing them against a traditional register machine approach. The article details implementing bytecode dispatch using match statements and explores how Rust's optimization features like explicit tail calls affect interpreter performance.
Background
Virtual machine dispatch is a well-studied area in systems programming, with techniques like threaded code, jump tables, and tail-call optimization being common approaches for building high-performance interpreters.
