How I speeded up my Rust builds on GitHub ~30 times
Rust is a great programming language, but it’s compiler is known to be slow. The main reason is that it checks so many things during the compilation in order to provides memory and concurrency safety. Like in many other cases, pipelines may be speeded up by caching, but it is very important to set the caching properly, otherwise it won’t help. Besides compiling your code may be slow, you also may want to use some cargo tools to lint and check your code and this will require to be compiled as well, if you don’t want to download binaries....
