• An Rust program consists of a tree of tasks, with their own stack
and sole ownership of allocated heap data
• Communicate through ports and channels
• Propagates failures to its parent (the task spawned this one) unless
unsupervise function is called.
• May be executed in parallel and are scheduled by the runtime
• Has its own GC (No global ”stop the world to clean up”)
