How to update your code to use associated constants

Assuming the following structure definition:

bitflags! {
  struct Something: u8 {
     const FOO = 0b01,
     const BAR = 0b10
  }
}

In 0.9 and older you could do:

let x = FOO.bits | BAR.bits;

Now you must use:

let x = Something::FOO.bits | Something::BAR.bits;
