Incremental rust builds up to 92x faster than cargo/rustc

blaze is a cargo-compatible build tool for Rust that speeds up incremental rebuilds dramatically. It keeps the project compiled in memory and, after an edit, recompiles only changed functions and patches them into the existing binary instead of relinking — with optional live edits to running programs. You use it like cargo: blaze run/build/test.

Why now: It just launched and is trending on Hacker News with a bold claim of incremental builds up to 92x faster than cargo/rustc, backed by published benchmarks.

Who it is for: Rust developers who want fast edit-build loops during development on macOS or Linux.
