Macro enumflags2::make_bitflags

macro_rules! make_bitflags {
    ( $enum:ident ::{ $($variant:ident)|* } ) => { ... };
}

make_bitflags! provides a succint syntax for creating instances of BitFlags<T>. Instead of repeating the name of your type for each flag you want to add, try make_bitflags!(Flags::{Foo | Bar}).

use enumflags2::{bitflags, make_bitflags};
#[bitflags]
#[repr(u8)]
#[derive(Clone, Copy, Debug)]
enum Test {
    A = 1 << 0,
    B = 1 << 1,
    C = 1 << 2,
}
let x = make_bitflags!(Test::{A | C});
assert_eq!(x, Test::A | Test::C);
