def spec_from_signature(

    sig: Signature,
    include_defaults: bool = True,
    base: Type[BaseConfiguration] = BaseConfiguration
) -> Tuple[Type[BaseConfiguration], Dict[str, Any]]

[view_source]

Creates a SPEC on base base1 for a function fwith signaturesig`.

All the arguments in sig that are valid SPEC hints and have defaults will be part of the SPEC. Special default markers for required SPEC fields dlt.secrets.value and dlt.config.value are sentinel string values with a type set to Any during typechecking. The sentinels are defined in dlt.common.typing module.

The name of a SPEC type is inferred from qualname of f and type will refer to f module and is unique for a module. NOTE: the SPECS are cached in the module by using name as an id.

Return value is a tuple of SPEC and SPEC fields created from a sig.
