Open-source project ra-jit introduces JIT compilation for Rust using rust-analyzer, enabling millisecond live edits in running programs. By incrementally rebuilding only modified functions, it cuts build time from 169ms to 7ms (24x speedup), though it currently lacks borrow checker support and limits live preview to Apple Silicon.
