Is it possible to refer to other flags within an enum using enumflags2?

Hey there, thanks so much for the great library.

I have searched through the various examples in the codebase and can't seem to find a way to do something similar to that below (using bitflags for demonstration):

bitflags! {
    struct Flags: u8 {
        const A = 1;
        const B = 1 << 1;
        const AB = Flags::A.bits() | Flags::B.bits(); // Is this possible with enumflags2?
    }
}

Thanks heaps
Fotis

You could write it like this:

#[bitflags]
#[derive(Clone, Copy)]
#[repr(u8)]
enum Flags {
    A = 1 << 0, // or omit the values if you don't care about the exact bits used
    B = 1 << 1,
}

impl Flags {
    const AB: BitFlags<Self> = make_bitflags!(Self::{A | B});
}

You could write it like this:

#[bitflags]
#[derive(Clone, Copy)]
#[repr(u8)]
enum Flags {
    A = 1 << 0, // or omit the values if you don't care about the exact bits used
    B = 1 << 1,
}

impl Flags {
    const AB: BitFlags<Self> = make_bitflags!(Self::{A | B});
}

Ah beautiful, thank you so much for your help. I'll close this issue now.
