Provides extension to rust enum
This crate provides Enumeration trait for rust enum with the following features
- implementation for common traits (Clone, Copy, Hash, etc.)
- getting number of variants through constant
Enumeration::VARIANT_COUNT - casting between index (of type
Enumeration::Index) and enumeration - attaching a constant value to each of the variants
- runtime representation of enumeration
use enumeration::{prelude::*, OutOfRangeError};
enumerate!(pub Foo(u8; i32 = 11)
Bar
Baz = 99
);
pub fn main() -> Result<Foo, OutOfRangeError> {
assert_eq!(Foo::Bar, Foo::variant(0)?);
assert_eq!(Foo::Baz.to_index(), 1);
assert_eq!(Foo::Bar.value(), 11);
assert_eq!(Foo::Baz.value(), 99);
let variants: Vec<Variant<_>> = vec![Foo::Bar.into(), SomeOtherExternalEnum::SomeVariant.into()];
assert_eq!(variants[0].cast::<Foo>(), Ok(Foo::Bar));
assert_eq!(variants[1].cast::<SomeOtherExternalEnum>(), Ok(SomeOtherExternalEnum::SomeVariant));
assert!(variants[1].cast::<Foo>().is_err());
}
