I tried to use serde's adjacently tagged serialization of enums with RON. But it does not seem to work. Unless I've something missing. Here is the example:
use serde::{Deserialize, Serialize};
#[derive(Serialize, Deserialize)]
#[serde(tag = "type", content = "data")]
enum TestEnum {
Name(String),
Index(u32),
}
fn main() {
use ron::{ser::to_string, de::from_str};
let source = TestEnum::Index(1);
let ron_string = to_string(&source).unwrap(); // this one is ok
let deserialized = from_str::<TestEnum>(&ron_string).unwrap(); // fails here
}However, the same test for json5 works fine. Am I doing something wrong here?
