Crate tyenum

Attribute macro for less verbose creation of enums having different types as variants. Also automatically implements From.

Usage:

struct A;
struct B;
struct C;
struct D;

#[tyenum]
enum Test {
    A,
    BB(B),
    C(C),
}

results in:

enum Test {
    A(A),
    BB(B),
    C(C),
}

impl From<A> for Test {
    fn from(variant: A) -> Self {
        Test::A(variant)
    }
}

impl From<B> for Test {
    fn from(variant: B) -> Self {
        Test::BB(variant)
    }
}

impl From<C> for Test {
    fn from(variant: C) -> Self {
        Test::C(variant)
    }
}
