REASY opened a new issue, #2866:
URL: https://github.com/apache/fory/issues/2866
### Feature Request
The code below does not compile
```Rust
macro_rules! impl_value {
($record:ident, $value:ident, { $($field:ident : $ty:ty = $expr:expr),*
$(,)? }) => {
#[derive(ForyObject)]
pub struct $value {
$(pub $field: $ty,)*
}
impl $record {
pub fn to_key_value(self) -> (String, $value) {
let Self {
feature_key,
$($field,)*
} = self;
let value = $value {
$($field: $expr,)*
};
(feature_key, value)
}
}
};
}
#[derive(Debug, Clone)]
pub struct KeyValue {
feature_key: String,
count: u64,
last_seen_event_time: DateTime<Utc>,
}
impl_value!(
KeyValue,
Value,
{
count: u64 = count,
last_seen_event_time: NaiveDateTime =
last_seen_event_time.naive_utc(),
}
);
#[test]
fn test_in_macro() {
let key_value = KeyValue {
feature_key: "test_key".to_string(),
count: 100,
last_seen_event_time: Utc::now(),
};
let (key, value) = key_value.clone().to_key_value();
assert_eq!(key, "test_key");
assert_eq!(value.count, 100);
assert_eq!(value.last_seen_event_time,
key_value.last_seen_event_time.naive_utc());
}
```
With slight modification of
[rust/fory-derive/src/object/read.rs](rust/fory-derive/src/object/read.rs)
compiler shows
```
