Crates are Rust's compilation unit, so splitting into many crates is equivalent to splitting into many object files in C++. It's true that splitting will often not improve compile time, but that applies just as much to C++. If your goal is to improve compile-time, then you need to think carefully about how you organize the crates. Keep in mind that generic / inline code will be recompiled for each crate using the code.
