URL: https://github.com/apache/avro/pull/1368#issuecomment-943329047
Here is a test case that properly constructs a POJO:
```rust
#[test]
fn test_from_value_with_union() -> TestResult<()> {
#[derive(Debug, Deserialize, PartialEq)]
struct StructWithMapInner {
map: Option<HashMap<String, i64>>,
}
#[derive(Debug, Deserialize, PartialEq)]
struct StructWithMap {
inner: StructWithMapInner,
}
let raw_map: HashMap<String, i64> = [
("one".to_string(), 1i64),
("three".to_string(), 3i64),
("two".to_string(), 2i64)
].iter().cloned().collect();
let map = raw_map.iter()
.map(|(k, v)| (k.clone(), Value::Long(*v)))
.collect();
let value = Value::Record(vec![(
"inner".to_owned(),
Value::Record(vec![
("map".to_string(), Value::Union(Box::new(Value::Map(map)))),
// ("map".to_string(), Value::Map(map)),
]),
)]);
let result: StructWithMap = crate::from_value(&value)?;
assert_eq!(result, StructWithMap{ inner: StructWithMapInner{ map:
Some(raw_map) }});
Ok(())
}
```
The key is that you need to use an `Option` for the `Union`.
Everything works without your changes.
Just put this test at the bottom of `de.rs` and run `cargo test
test_from_value_with_union`

> Rust deserializer: add missing matches to deserialize_any union and string/map

> When deserializing complex Avro schemas using from_value::<T> to map the data
> to a struct, we get errors even if the Record itself has been deserialized
> successfully.
> These errors come from the fact that `deserialize_any` from de.rs is missing
> some matches.
