Enum Serialization with Tag

 # serde_yaml -- every variant starts with a !Tag
 enser:
-- Tbd
-- None
+- !Tbd null
+- !None null
 - !Some 123
 - !Named
   value: 456

 # serde_json -- every variant is an object
 {
   "enser": [
-    "Tbd",
-    "None",
+    { "Tbd": null },
+    { "None": null },
     { "Some": 123 },
     { "Named": { "value": 456 } }
   ]
 }

Usage

Add the following to Cargo.toml

enser = "0.1.4"

#[enser::enser] // <-- just add this
                // Note: It *must* come above `#[derive(Clone, Deserialize, Serialize)]`
#[derive(Clone, Debug, Deserialize, Serialize)]
enum MyEnum {
    Tbd,
    None,
    Some(u32),
    Named { value: u32 },
}

Generics

This will automatically work for generic types:

#[enser::enser]
#[derive(Clone, Debug, Deserialize, Serialize)]
enum MyEnum<T, U> {
    None,
    Some(T),
    Named { value: U },
}

However, it also adds a Clone bound to each type parameter, so all impl blocks will require the type parameters to have a Clone bound.

If you can find a way for the generics example to work without causing the Clone bound propagation, then please let me know / submit a pull request!
