public protocol SemigroupK

SemigroupK is a Semigroup that operates on kinds with one type parameter.

  • Combines two values of the same type in the context implementing this instance.

    Implementations of this method must obey the associative law:

    combineK(fa, combineK(fb, fc)) == combineK(combineK(fa, fb), fc)

    Declaration

    Swift

    static func combineK<A>(
    _ x: Kind<Self, A>,
    _ y: Kind<Self, A>) -> Kind<Self, A>

    Parameters

    x

    Left value in the combination.
    y

    Right value in the combination.

    Return Value

    Combination of the two values.
