Classes

DataLoadingBlockTypes
DataLoadingBlockTypes(*args)
Bases: _BaseEnum
Base class for typing purposes.
Concrete enumeration types should be defined within the scope of their implementation or application. To define a concrete enumeration type, one must subclass this class as follows:
class MyLoadingBlockTypes(DataLoadingBlockTypes, Enum):
MY_KEY: str 'myKey'
MY_OTHER_KEY: str 'myOtherKey'
Subclasses must respect the following conditions: - All fields must be str; - All field values must be unique.
Warning
This class must always be empty as it is not allowed to contain any fields!
