polyfactory.value_generators.constrained_collections.handle_constrained_collection(collection_type: Callable[..., T], factory: type[BaseFactory[Any]], field_meta: FieldMeta, item_type: Any, max_items: int | None = None, min_items: int | None = None, unique_items: bool = False, field_build_parameters: Any | None = None, build_context: BuildContext | None = None) → T

Generate a constrained list or set.

Parameters:

• collection_type – A type that can accept type arguments.

• factory – A factory.

• field_meta – A field meta instance.

• item_type – Type of the collection items.

• max_items – Maximal number of items.

• min_items – Minimal number of items.

• unique_items – Whether the items should be unique.

• field_build_parameters – Any build parameters passed to the factory as kwarg values.

• build_context – BuildContext data for current build.

Returns:

A collection value.
