Emitting metadata early could double Rust build speeds

Original: Emitting metadata early makes building/checking Rust up to twice as fast

A change that emits Rust compiler metadata earlier in the build process makes building and checking code up to twice as fast, according to a project shared on GitHub. Developers are discussing what the speedup means for compile times, which are a common complaint in the Rust community, and how the technique might be adopted more widely.

Why now: Faster Rust compile times are a long-standing pain point, so a potential doubling of build speed draws wide developer interest.
