Trait async_graphql::Type

pub trait Type {
    fn type_name() -> Cow<'static, str>;
    fn create_type_info(registry: &mut Registry) -> String;

    fn qualified_type_name() -> String { ... }
    fn introspection_type_name(&self) -> Cow<'static, str> { ... }
}

Represents a GraphQL type.

All GraphQL types implement this trait, such as Scalar, Object, Union …

Required methods

fn type_name() -> Cow<'static, str>

Type the name.

fn create_type_info(registry: &mut Registry) -> String

Create type information in the registry and return qualified typename.

Provided methods

fn qualified_type_name() -> String

Qualified typename.

fn introspection_type_name(&self) -> Cow<'static, str>

Introspection type name

Is the return value of field __typename, the interface and union should return the current type, and the others return Type::type_name.
