URL: https://github.com/apache/avro/pull/1393#issuecomment-966756569
I checked and ur solution seems to be wrong if we have a union like this
["A", "B"]
where A and B are like this –
// A and B are the same except the name.
let schema_str_1 = r#"{
"name": "A",
"type": "record",
"fields": [
{"name": "field_one", "type": "float"}
]
}"#;
let schema_str_2 = r#"{
"name": "B",
"type": "record",
"fields": [
{"name": "field_one", "type": "float"}
]
}"#;
in this case, the schema found by a value will always be "A"'s schema.
this also applies to A, B being "fixed" type, which seems more plausible in
reallife (for example A =
{"name": "fieldA", "type": "fixed", "size": 10}
, B =
{"name": "fieldB", "type": "fixed", "size": 10}
)
here is my PR for these scenario . https://github.com/apache/avro/pull/1396

> currently there's no support for named type in avro's Union type in rust.
> as stated in this comment of the UnionSchma struct

> // **NOTE** that this approach does not work for named types, and will have
