leaspy.utils.functional

fCallable: The original function. The named parameters to be sent in f should be: positional, positional-or-keyword, or variadic arguments. It can also have some keyword-only arguments, but they should be fixed once for all with attribute kws.
parameterstuple[str, …]: Assigned names, in order, for positional parameters of f.
kwsNone (default) or dictionary[str, Any]: Some optional fixed keyword parameters to pass upon function calls.

Notes

We do not implement the mapping of keyword-only to renamed keyword-only parameters for now since it is not needed and would make the logic more complex. Particularly due to the existence of positional-only parameters.

f: Callable[Ellipsis, RT]

parameters: Tuple[str, Ellipsis]

kws: leaspy.utils.typing.KwargsType | None = None

call(named_params)

Call the underlying function with the correct positional arguments, retrieved by parameter names in input variables.

Parameters:: named_params (Mapping[str, Any])
Return type:: RT

then(g, **g_kws)

Return a new NamedInputFunction applying (g o f) function.

Parameters:: g (Callable[[RT], S])

static bound_to(f, check_arguments=None)

Return a new factory to create new NamedInputFunction instances that are bound to the provided function.

Parameters:

f (Callable[Ellipsis, RT])
check_arguments (Optional[Callable[[Tuple[str, Ellipsis], leaspy.utils.typing.KwargsType], None]])

get_named_parameters(f)

Get the names of parameters of the input function f, which should be a NamedInputFunction or a function with keyword-only parameters.

Parameters:: f (Callable)
Return type:: Tuple[str, Ellipsis]
