Rust compiler daemon on rust-analyzer: fast incremental cargo builds and live edits to running programs. Try: nix run github:indexable-inc/ra-jit
ra-jit is a Rust compiler daemon built on rust-analyzer that speeds up incremental builds and enables live code editing: save a file and a running program picks up the changed functions in milliseconds, preserving its state. It works through normal cargo commands like build, run, test, and check, though live edits currently only work on macOS Apple silicon.
Why now: It's getting attention on Hacker News for claiming 24x faster Rust compilation than incremental cargo builds, with a live-editing Game of Life demo.
Who it is for: Rust developers—especially those building games, GUIs, or long-running apps—who want instant feedback while iterating on code.
