I highly recommend checking out makepad [1] - they have +100k of rust code and the compile time is around 10-15 seconds on commodity hardware.

However they are obsessed about performance. They reason for such speedy compile times is that makepad almost has no dependencies.

IMHO Makepad also has an exceptionally readable Rust code style, which is a very rare thing (maybe that simple Rust style even contributes to the good build times, dunno) - but also: from the pov of a C programmer, 200 kloc in 10..15 seconds is still quite bad ;)

How quickly can you verify the memory safety of that C program in addition to compiling it though? When comparing like to like, C no longer looks so fast.

Rust code with unsafe still compiles slowly. And safe subsets of C still compile quickly.

[timschmidt]

That is exactly the opposite of my experience.

I used actix web, could it be the reason for slow compile?

[matesz]

I am not completely sure, but I think pretty much all frameworks in Rust have complex dependencies and codebase not optimized for fast compile times. You could check out Axum [1], at the first glance seems similar to actix [2]. Both use tokio which is by itself pretty big I think.

Folks at makepad poured enormous effort in keeping dependency graph minimal.
