Rust builds can be up to twice as fast with early metadata
Original: Emitting metadata early makes building/checking Rust up to twice as fast
A new optimization for the Rust compiler emits metadata earlier in the build process, cutting build and check times by up to half on some projects. The change is drawing attention among developers, who see faster compile times as one of the biggest remaining pain points for Rust adoption. The work is available on GitHub for testing and review.
Why now: Compile speed is one of the most common complaints about Rust, so a potential 2x improvement generates strong interest.
