EnumFlags

EnumFlags is a csharp like enum flags implementation.

Example

```rust use enum_flags::EnumFlags;

[repr(u8)]

[derive(EnumFlags, Copy, Clone, PartialEq)]

enum Flags{ None = 0, A = 1, B = 2, C = 4 } fn main() { let e1: Flags = Flags::A | Flags::C; let e2 = Flags::B | Flags::C;

assert_eq!(e1 | e2, Flags::A | Flags::B | Flags::C); // union
assert_eq!(e1 & e2, Flags::C); // intersection
assert_eq!(e1 ^ e2, Flags::A | Flags::B); // toggle
assert_eq!(e1 & (!Flags::C), Flags::A); // deletion
assert_eq!(e1 - Flags::C, Flags::A); // deletion

assert_eq!(format!("{:?}", e1).as_str(), "(Flags::A | Flags::C)");
assert!(e1.has_a());
assert!(!e1.has_b());
assert!(e1.has_flag(Flags::C));

} ```
