elad-yosifon opened a new issue, #247:
URL: https://github.com/apache/avro-rs/issues/247
I tried to play around with the proc-macro, and was able to make this test
pass:
```rust
#[test]
fn avro_flatten_fields() {
#[derive(Debug, Serialize, Deserialize, AvroSchema, Clone,
PartialEq)]
struct Nested {
a: bool,
}
#[derive(Debug, Serialize, Deserialize, AvroSchema, Clone,
PartialEq)]
struct Foo {
#[serde(flatten)]
nested: Nested,
b: i32,
}
let schema = r#"
{
"type":"record",
"name":"Foo",
"fields": [
{
"name":"a1",
"type":"boolean"
},
{
"name":"b",
"type":"int"
}
]
}
"#;
let schema = Schema::parse_str(schema).unwrap();
let derived_schema = Foo::get_schema();
if let Schema::Record(RecordSchema { name, fields, .. }) =
&derived_schema {
assert_eq!("Foo", name.fullname(None));
for field in fields {
match field.name.as_str() {
"a" | "b" => {
// expected
},
name @ _ => {
panic!("Unexpected field name '{name}'")
}
}
}
} else {
panic!(
"Foo schema must be a record schema: {derived_schema:?}"
)
}
assert_eq!(schema, derived_schema);
// deserializing not support
// serde_assert(Foo {
// nested: Nested { a: true },
// b: 321,
// });
}
```
but while running the other tests, it broke the `serde(rename)` related
tests since the schema code genrator changed in order to allow nested fields to
be pushed, and the tests verify the code generation.
I am having a hard time implementing this correctly mainly due to my lack of
familiarity with the project.
