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>
impl<'r, S: 'r> Registry<'r, S>
sourcepub fn new(types: FnvHashMap<Name, MetaType<'r, S>>) -> Self
pub fn new(types: FnvHashMap<Name, MetaType<'r, S>>) -> Self
Constructs a new Registry
out of the given types
.
sourcepub fn get_type<T>(&mut self, info: &T::TypeInfo) -> Type<'r>
pub fn get_type<T>(&mut self, info: &T::TypeInfo) -> Type<'r>
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.
sourcepub fn field<T>(&mut self, name: &str, info: &T::TypeInfo) -> Field<'r, S>
pub fn field<T>(&mut self, name: &str, info: &T::TypeInfo) -> Field<'r, S>
Creates a Field
with the provided name
.
sourcepub fn arg<T>(&mut self, name: &str, info: &T::TypeInfo) -> Argument<'r, S>
pub fn arg<T>(&mut self, name: &str, info: &T::TypeInfo) -> Argument<'r, S>
Creates an Argument
with the provided name
.

info: &T::TypeInfo
) -> Argument<'r, S>
pub fn arg_with_default<T>( &mut self, name: &str, value: &T, info: &T::TypeInfo ) -> Argument<'r, S>
Creates an Argument
with the provided default value
.

type.
Specifying expected_size
will be used to ensure that values of this
type will always match it.
sourcepub fn build_nullable_type<T>(&mut self, info: &T::TypeInfo) -> NullableMeta<'r>
pub fn build_nullable_type<T>(&mut self, info: &T::TypeInfo) -> NullableMeta<'r>
Creates a NullableMeta
type.
sourcepub fn build_object_type<T>(
&mut self,
info: &T::TypeInfo,
fields: &[Field<'r, S>]
) -> ObjectMeta<'r, S>
pub fn build_object_type<T>( &mut self, info: &T::TypeInfo, fields: &[Field<'r, S>] ) -> ObjectMeta<'r, S>
Creates an ObjectMeta
type with the given fields
.
sourcepub fn build_enum_type<T>(
&mut self,
info: &T::TypeInfo,
values: &[EnumValue]
) -> EnumMeta<'r, S>
pub fn build_enum_type<T>( &mut self, info: &T::TypeInfo, values: &[EnumValue] ) -> EnumMeta<'r, S>
Creates an EnumMeta
type out of the provided values
.
sourcepub fn build_interface_type<T>(
&mut self,
info: &T::TypeInfo,
fields: &[Field<'r, S>]
) -> InterfaceMeta<'r, S>
pub fn build_interface_type<T>( &mut self, info: &T::TypeInfo, fields: &[Field<'r, S>] ) -> InterfaceMeta<'r, S>
Creates an InterfaceMeta
type with the given fields
.
sourcepub fn build_union_type<T>(
&mut self,
info: &T::TypeInfo,
types: &[Type<'r>]
) -> UnionMeta<'r>
pub fn build_union_type<T>( &mut self, info: &T::TypeInfo, types: &[Type<'r>] ) -> UnionMeta<'r>
Creates an UnionMeta
type of the given types
.
sourcepub fn build_input_object_type<T>(
&mut self,
info: &T::TypeInfo,
args: &[Argument<'r, S>]
) -> InputObjectMeta<'r, S>
pub fn build_input_object_type<T>( &mut self, info: &T::TypeInfo, args: &[Argument<'r, S>] ) -> InputObjectMeta<'r, S>
Creates an InputObjectMeta
type with the given args
.
