Untagged deserialization of Query<Result<T, U>>

[avdb13]

Summary

Currently this works but it's ugly and verbose:

#[derive(Deserialize)]
#[serde(untagged)]
pub enum AuthResult {
    Ok(AuthorizationResponse),
    Err(ClientError),
}

I came up with the following snippet but it doesn't compile since I can't reuse deserializer.

#[derive(Deserialize)]
pub struct AuthResult(
    #[serde(deserialize_with = "de_auth_result")] Result<AuthResponse, ClientError>,
);

fn de_auth_result<'de, D>(deserializer: D) -> Result<Result<AuthResponse, ClientError>, D::Error>
where
    D: Deserializer<'de>,
{
    AuthResponse::deserialize(deserializer)
        .map(Result::Ok)
        .or_else(|_| ClientError::deserialize(deserializer).map(Result::Err))
}

The problem is that the query might contain an error or successful response and I wanna have access to the error to trace it.
