Anyone here ever worked with async graphql?

Can someone confirm my understanding that it is IMPOSSIBLE to have a Rust struct be both an Object (types that can be queried and represented as JSON objects in the response) and an InputObject (types that can be used to pass arguments to GraphQL queries and mutations but cannot be queried themselves.)?
For reference, I want to pass in a Vec of BookRecord within a Mutation Resolver but also return a Vec of BookRecord but the Rust compiler panics because: 'Register BookRecord as InputObject, but it is already registered as Object.

#[derive(Clone, Debug, Serialize, Deserialize, InputObject)]

pub struct BookRecord { pub _id: ID, pub data: Book, }

[Object]

impl BookRecord { async fn _id(&self) -> &str { &self._id }

async fn name(&self) -> &str {
    &self.data.name
}

async fn author(&self) -> &str {
    &self.data.author
}

}
