@chaokunyang So Fory needs to support handling enum like this.
```rust
enum Token {
Plus,
Number(i64),
Ident(String),
Assign { target: String, value: i32 },
Other(Option<i64>),
}
```
Generated code:
```rust
impl Token{
fn serialize(&self, context: &mut WriteContext) {
match self {
Self::Plus => {
context.write_i8(0);
}
Self::Number(f1) => {
context.write_i8(1);
i64::write(*f1, context);
}
Self::Ident(f1) => {
context.write_i8(2);
String::write(f1, context);
}
Self::Assign { target, value } => {
context.write_i8(3);
String::write(target, context);
i32::write(*value, context);
}
Self::Other(f1) => {
context.write_i8(4);
Option::<i64>::write(f1, context);
}
}
}
fn deserialize(context: &mut ReadContext) -> Self {
let tag = context.read_i8();
match tag {
0 => Self::Plus,
1 => {
let f1 = i64::read(context);
Self::Number(f1)
}
2 => {
let f1 = String::read(context);
Self::Ident(f1)
}
3 => {
let target = String::read(context);
let value = i32::read(context);
Self::Assign { target, value }
}
4 => {
let f1 = Option::<i64>::read(context);
Self::Other(f1)
}
_ => panic!("Unknown tag for Token: {}", tag),
}
}
}
```
