Expand description

A type registry used to build schemas

The registry gathers metadata for all types in a schema. It provides convenience methods to convert types implementing the GraphQLType trait into Type instances and automatically registers them.

Fields§

§types: FnvHashMap<Name, MetaType<'r, S>>

Currently registered types

Implementations§

source§

impl<'r, S: 'r> Registry<'r, S>

source

pub fn new(types: FnvHashMap<Name, MetaType<'r, S>>) -> Self

Constructs a new Registry out of the given types.

source

pub fn get_type<T>(&mut self, info: &T::TypeInfo) -> Type<'r>
where T: GraphQLType<S> + ?Sized, S: ScalarValue,

Returns a Type instance for the given GraphQLType, registered in this Registry.

If this Registry hasn’t seen a Type with such GraphQLType::name before, it will construct the one and store it.

where T: GraphQLType<S> + FromInputValue<S>, S: ScalarValue,

Creates an Argument with the provided name.

where T: GraphQLType<S> + ?Sized, S: ScalarValue,

source

pub fn build_interface_type<T>( &mut self, info: &T::TypeInfo, fields: &[Field<'r, S>] ) -> InterfaceMeta<'r, S>
where T: GraphQLType<S> + ?Sized, S: ScalarValue,

Creates an InterfaceMeta type with the given fields.

source

pub fn build_union_type<T>( &mut self, info: &T::TypeInfo, types: &[Type<'r>] ) -> UnionMeta<'r>
where T: GraphQLType<S> + ?Sized, S: ScalarValue,

Creates an UnionMeta type of the given types.

source

pub fn build_input_object_type<T>( &mut self, info: &T::TypeInfo, args: &[Argument<'r, S>] ) -> InputObjectMeta<'r, S>
where T: GraphQLType<S> + FromInputValue<S>, T::Error: IntoFieldError<S>, S: ScalarValue,

Creates an InputObjectMeta type with the given args.
