Can not have an impl block for `BitFlags<MyFlags>`

[de-vri-es]

Because the BitFlags type comes from the enumflags2 crate, we can not add our own impl blocks for it or impl traits for it.

Would you be interested in an additional macro that allows you to define your own BitFlags type for a specific BitFlag enum?

#[bitflags]
#[repr(u8)]
#[derive(Copy, Clone, Debug, PartialEq)]
enum Flags {
    A = 0b0001,
    B = 0b0010,
    C, // unspecified variants pick unused bits automatically
    D = 0b1000,
}

#[flagset(Flags)]
struct Status;

// Yaay, we can do this:
impl Status {
  pub fn priority(&self) -> u8 {
     if self.contains(Flags::A) {
       1
     } else {
       2
     }
  }
}
