Concurrency

One of the rusts major goal is to handle [[concurency]] safely and efficiently, where parts of program are executed at the same time. By [[ownership]] and [[type checking]], many [[concurency errors]] are thrown at the [[compile time]].

Concurrency vs parallelism¶

In concurrency, suppose we have one [[CPU core]] and three [[process]]es that are being ran at the same time. The CPU will switch between these processes using an [[algorithm]] like [[Round Robin]], saving the progress of it.

In Parallelism, the CPU will have more than 1 core and it will be able to run more than 1 process at the same time while still using concurrency to switch between the processes.
