The making of Suru part 3: Multitasking
The second part of building Suru is constructing a build graph. A build graph is almost certainly necessary in the context of multithreading because of the presence of diamond dependencies. Constructing a graph in Rust isn’t too bad, but does require a little big of fandangling. Rc, Arc, Refcell, Mutex, RwLock??? I’ve seen some people get confused between the various constructs Rust has surrounding multithreading, but if you have a context in C++ multithreading it’s not very complicated....
