The compiler has to bootstrap itself so incremental compilation won't decrease the build times. Splitting up crates into many crates does allow for incremental compilation, but it will also increase the *total* build time, since work is being redone for any generic or cross-crate inlined functions. The final binary will also be larger and slower than using a single crate, so supporting link-time optimization for release builds is important. _______________________________________________ Rust-dev mailing list [email protected] https://mail.mozilla.org/listinfo/rust-dev
