# Macro attributes
| Attribute | description | Type | Optional |
|---------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|--------------|----------|
| name | Oneof input object name | string | Y |

# Examples
```rust

#[derive(OneofObject)]
enum MyInputObject {
A(i32),
B(String),
}
struct Query;
#[Object]
impl Query {
async fn value(&self, input: MyInputObject) -> String {
match input {
MyInputObject::A(value) => format!("a:{}", value),
MyInputObject::B(value) => format!("b:{}", value),
}
}
}
# tokio::runtime::Runtime::new().unwrap().block_on(async move {
let schema = Schema::new(Query, EmptyMutation, EmptySubscription);
let res = schema.execute(r#"
{
value1: value(input:{a:100})
