ENUM

GraphQLNullable

1public enum GraphQLNullable<Wrapped>: ExpressibleByNilLiteral

Indicates the presence of a value, supporting both nil and null values.

In GraphQL, explicitly providing a null value for an input value to a field argument is semantically different from not providing a value at all (nil). This enum allows you to distinguish your input values between null and nil.

• See: GraphQLSpec - Input Values - Null Value
