Functor

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

Class Functor is a generic class that implements the Functor type class.

Parameters: value (T) – The value of the functor.
Returns: A functor with the given value.

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

Apply a function to the value of the functor.

Parameters: func (Callable[["Functor[T]"], "Functor[S]"]) – The function to apply.
Returns: A functor with the value of the functor after applying the function.

get() → fpylib.types._T[source]

Get the value of the functor.

Returns: The value of the functor.

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

This function is a functor’s fmap function.

Parameters

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

Returns

Functor[S]
