A GraphQL input object type

Examples

use async_graphql::{dynamic::*, value, Value};

let my_input = InputObject::new("MyInput")
    .field(InputValue::new("a", TypeRef::named_nn(TypeRef::INT)))
    .field(InputValue::new("b", TypeRef::named_nn(TypeRef::INT)));

let query = Object::new("Query").field(
    Field::new("add", TypeRef::named_nn(TypeRef::INT), |ctx| {
        FieldFuture::new(async move {
            let input = ctx.args.try_get("input")?;
            let input = input.object()?;
            let a = input.try_get("a")?.i64()?;
            let b = input.try_get("b")?.i64()?;
            Ok(Some(Value::from(a + b)))
        })
    })
    .argument(InputValue::new("input", TypeRef::named_nn(my_input.type_name())))
);


let schema = Schema::build(query.type_name(), None, None)
    .register(my_input)
    .register(query)
    .finish()?;

assert_eq!(
   schema
       .execute("{ add(input: { a: 10, b: 20 }) }")
       .await
       .into_result()
       .unwrap()
       .data,
   value!({ "add": 30 })
);

Implementations§

Create a GraphQL input object type

Set the description

Reference: https://www.apollographql.com/docs/federation/federated-types/federated-directives/#applying-metadata

Add a field

Indicates this Input Object is a OneOf Input Object

Returns the type name
