Optimizing Rust Value Representation with 64-Bit Low-Bit Tagging to Improve Interpreter Performance

#rust #performance-optimization #memory-management

The article describes optimizing a Rust-based interpreter by replacing a 16-byte enum with a 64-bit low-bit tagging scheme, achieving a 17% performance improvement through memory efficiency and specialized value representation. This approach encodes integers, floats, pointers, and immediates using bitwise operations to reduce memory overhead while maintaining fast type discrimination and comparison operations.
