Splitting uv's main crate into 14 crates cut incremental build times by 30-40% with agents
Vjeux · x · 2026-10-15
Cargo compiles per-crate: independent crates build in parallel and unaffected ones are skipped entirely. charliermarsh split uv's primary crate (46k lines) into 14 crates (6k lines each), speeding up incremental builds by 30-40% — a refactor he calls utterly miserable before coding agents. A tidy example of agents eating mechanical-but-tedious large-scale refactors.
