So many complaints above surface-level syntax here.

> press "shift 3 bracket shift 9 shift 0 bracket" at the top of my structs

Just use an IDE and you can press alt+enter. Same thing you do in Java when writing getters and setters for your AbstractFactoryBeans.

> "let mut" could have been "var"

The "mut" does not belong to the "let", it belongs to the variable name.

  let (read_only, mut read_write) = (1, 2);

> Passing "self" as the first argument was bullshit

Explicit is better than implicit. I quite like the names in the argument list to match the set of names available in the function, rather than having an extra keyword (`static`) that you add to remove a function parameter.
