    I recall a talk about makepad.dev, I think it was by Rik Arends, that explained how they achieved outstanding compilation times in rust for makepad.

    I can't find that talk again, but it was quite interesting: the rust compiler is fast, but often times it has to perform a lot of unnecessary checks because crates contain more stuff than needed. By stripping unnecessary work, the makepad team made building pretty fast.
