Isn't it a basic C compiler feature that you can compile a file as an Object, and then link the objects into a single executable? Then you only recompile the file you changed.

Not sure what I'm missing.

That's how Rust works already.

The problem has been created by Docker which destroys all of the state. If this was C, you'd also end up losing all of the object files and rebuilding them every time.

Nope, reread the article, docker wasn't part of the problem it's part of the 'solution' according to OP.
