Rust has no more runtime than c. Threads are implemented in the standard library, but they'll only be used if you explicitly create one (or a library you are using does). Fork works fine :)

Rust has a very different design philosphy to c, and in that respect you are right that it isn't a complete replacement. That said, Rust is good for far more than just multithreading. It solves memory safety as well as tgread safety.

It can work but it’s quite unsafe. The standard library doesn’t make any guarantees about fork safety. The language itself doesn’t understand what fork is, and so can’t guarantee anything.
