Are reference values copied in Rust? [duplicate]

Question

Am I correct to assume that, for the following code

let a = vec![1, 2, 3];
let b = &a;
let c = b;

The memory presentation will be something like this, assuming the value of b is "B"?

  _            _
b|B|         c|B|
  |____________|
  |
  V
  _________
a|_________|

I'm only asking about immutable references, as there can be only 1 mutable reference, as far as I remember.

Answer 1

Yes, this is correct.

In Rust terms, &T is Copy, which means that it can be copied bitwise without transferring ownership.
