Mutable Borrows (&mut)

help
9

There was a recentish thread with a lot of working through mental models for how reborrows work:

  • Starting here
    • Skip halfway down the comment to "Finally, I'd like to outline..."
    • The main reason to read this portion is it introduces a "chain of exclusive access" concept referred back to later
  • Then here through the end of the thread
    • In this part we examine why "no two &mut at the same time" is too simplistic of a model
    • And the following comments work through a few examples

It also contains links to some technical resources on the implementation and why they're sound (but I personally find those harder to consume).
