name_variant

生成打印枚举变体名称的方法。

示例

 use name_variant::NamedVariant;

 #[derive(NamedVariant)]
 enum TestEnum {
     A,
     B(),
     C(i32, i32),
     D { _name: String, _age: i32 },
     VariantTest,
 }

 fn main() {
     let x = TestEnum::C(1, 2);
     assert_eq!(x.variant_name(), "C");

     let x = TestEnum::A;
     assert_eq!(x.variant_name(), "A");

     let x = TestEnum::B();
     assert_eq!(x.variant_name(), "B");

     let x = TestEnum::D {_name: "Jane Doe".into(), _age: 30 };
     assert_eq!(x.variant_name(), "D");

     let x = TestEnum::VariantTest;
     assert_eq!(x.variant_name(), "VariantTest");
 }
