Renaming tags in unions

[ejpcmac]

Hello, is there any way to rename a tag?

Let’s say I have this YAML file, featuring a serialised something that can be either local or distant, internally tagged:

something:
    type: local # or distant
    # other fields

Let’s say I had this in Rust with serde, which successfully allows to deserialise the file into a Config:

#[derive(Debug, Deserialize)]
struct Config {
    something: Something,
}

#[derive(Debug, Deserialize)]
#[serde(tag = "type", rename_all = "snake_case")]
enum Something {
    Local(SomethingLocal),
    Distant(SomethingDistant),
}

#[derive(Debug, Deserialize)]
struct SomethingLocal { ... }

#[derive(Debug, Deserialize)]
struct SomethingDistant { ... }

Now, the closest I’ve found in Python is to write this:

@dataclass
class SomethingLocal:
    # ...

@dataclass
class SomethingDistant:
    # ...

@serde(tagging=InternalTagging("type"))
@dataclass
class Config:
    something: Union[SomethingLocal, SomethingDistant]

But this means I need to have a YAML file like this instead:

something:
    type: SomethingLocal # or SomethingDistant
    # other fields

As there is no such thing as an enum with fields in Python, I don’t see how to properly name the variants. Is there anyway with pyserde?
