Trait enumflags2::RawBitFlags

pub trait RawBitFlags: Copy + Clone + 'static + RawBitFlags {
    fn empty() -> BitFlags<Self> { ... }
    fn all() -> BitFlags<Self> { ... }
}

A trait automatically implemented by derive(BitFlags) to make the enum a valid type parameter for BitFlags<T>.

Provided methods

fn empty() -> BitFlags<Self>

Create a BitFlags with no flags set (in other words, with a value of 0).

This is a convenience reexport of BitFlags::empty. It can be called with MyFlag::empty(), thus bypassing the need for type hints in some situations.

#[derive(Clone, Copy, PartialEq, Eq, BitFlags)]
enum MyFlag {
    One = 1 << 0,
    Two = 1 << 1,
    Three = 1 << 2,
}

use enumflags2::RawBitFlags;

let empty = MyFlag::empty();
assert!(empty.is_empty());
assert_eq!(empty.contains(MyFlag::One), false);
assert_eq!(empty.contains(MyFlag::Two), false);
assert_eq!(empty.contains(MyFlag::Three), false);

fn all() -> BitFlags<Self>

Create a BitFlags with all flags set.

This is a convenience reexport of BitFlags::all. It can be called with MyFlag::all(), thus bypassing the need for type hints in some situations.

#[derive(Clone, Copy, PartialEq, Eq, BitFlags)]
enum MyFlag {
    One = 1 << 0,
    Two = 1 << 1,
    Three = 1 << 2,
}

use enumflags2::RawBitFlags;

let empty = MyFlag::all();
assert!(empty.is_all());
assert_eq!(empty.contains(MyFlag::One), true);
assert_eq!(empty.contains(MyFlag::Two), true);
assert_eq!(empty.contains(MyFlag::Three), true);
