Ruff creator surveys fast-iteration Rust compilers: 'there is something to this idea of a JIT for Rust'
charliermarsh · x · 2026-10-21
Charlie Marsh, creator of Ruff, kicks off a thread on emerging Rust forks/alternative implementations focused on iteration speed. He highlights the Relax project, a Rust JIT that generates native code as the program runs, with its own compiler frontend and backend, and notes features like hot reloading. He argues the broader idea of a "JIT for Rust" designed for fast iteration has real promise, though compiler compatibility remains a shared concern.
