Applicative

class fpylib.functors.applicative.Applicative(value: Optional[fpylib.types._T] = None)[source]

apply(func: fpylib.functors.functor.Functor[Callable[[fpylib.types._T], fpylib.types._S]]) → fpylib.functors.functor.Functor[fpylib.types._S][source]

Apply a wrapped function to a wrapped value of the functor.

Parameters: func – A wrapped function.
Returns: A wrapped value of the functor.

fpylib.functors.applicative.apply(func: fpylib.functors.functor.Functor[Callable[[fpylib.types._T], fpylib.types._S]], ft: fpylib.functors.functor.Functor[fpylib.types._T]) → fpylib.functors.functor.Functor[fpylib.types._S][source]

This the function applicative to a functor that wraps a function and a functor.

Parameters

func – Functor[Callable[[T], S]]
ft – Functor[T]

Returns

Functor[S]

fpylib.functors.applicative.lift_a2(func: Callable[[fpylib.types._T, fpylib.types._T], fpylib.types._S], f1: fpylib.functors.functor.Functor[fpylib.types._T], f2: fpylib.functors.functor.Functor[fpylib.types._T]) → fpylib.functors.functor.Functor[fpylib.types._S][source]

This is the version Pythonic to liftA2 from Haskell.

Parameters

func – Callable[[T, T], S]
f1 – Functor[T]
f2 – Functor[T]

Returns

Functor[S]
