Alt<KT, A> mixin

Alt type class identifies an associative operation on a type constructor.

It provides an alt function used to return an alternative value when the current one represents a failure (for example, None for Option).

Superclass constraints

Methods

alt(HKT<KT, A> orElse()) → HKT<KT, A>

map<B>(B f(A a)) → HKT<KT, B>

Return type is HKT<G, B>, which expresses the fact that what we return is using exactly the same type constructor represented by the brand G
