-------------------------
Summary: Serde flatten is not supported when deserializing
Key: AVRO-3692
URL: https://issues.apache.org/jira/browse/AVRO-3692
Project: Apache Avro
Issue Type: Improvement
Components: rust
Reporter: Ten
The following:
```rust
#[test]
fn test_from_value_struct_flatten() {
#[derive(Deserialize, PartialEq, Debug)]
struct S1 {
f1: String,
#[serde(flatten)]
inner: S2,
}
#[derive(Deserialize, PartialEq, Debug)]
struct S2 {
f2: String,
}
let expected = S1 {
f1: "Hello".to_owned(),
inner: S2 {
f2: "World".to_owned(),
},
};
let test = Value::Record(vec![
("f1".to_owned(), "Hello".into()),
("f2".to_owned(), "World".into()),
]);
let final_value: S1 = from_value(&test).unwrap();
assert_eq!(final_value, expected);
}
```
fails to deserialize.
This is due to serde hinting for map deserialization when structs contain
flatten. It is super easy to fix, I'm opening a PR.
