How does Rust's compile times compare with those of C++?

• steveklabnik 11y ago
  We don't have a whole lot of data, but generally faster. I can't seem to find the blog post now, but someone ported their raytracer from C++ to Rust, and the compile time was... half? I think?

    Do you mean this[1] port? I can't remember one that had statistics on incremental builds during development, unfortunately.

      Yes! That one. Right now, Rust only builds each crate in paralell, we don't support incremental re-builds within crates. There's an RFC already though, and build times are gonna be a big focus of the next release cycle or two.

    Wait, really? Wow. I always thought Rust was slower to compile. Huh.

      Yeah, people say Rust is slow to compile, but when they say that, they aren't generally talking about C++.
