Copy & Clone : Various methods of keeping track of References (both single threaded(Rc) and multi-threaded (Arc,Mutex)

copy-default.rs

fn main(){
  let p1 = 1_000;
  let p2 = p1; // Copy

  let v1 = Box::new(200); stack pointer but value on the heap
  let v2 = v1; // Clone
}

refrence-counters.rs

use std::rc::Rc;
fn main(){
  let p1 = Rc::new(5);
  let p2 = Rc::clone(&p1); // ref only 'Clone'

  let v1 = Rc::new(5);
  let v2 = v1.clone(); // both ref & value Clone
  println!("p1: {:?}, p2: {:?}",p1,p2);
  println!("v1: {:?}, v2: {:?}",v1,v2);
}
