KTypeClass

trait KTypeClass[C[_[_]]] extends AnyRef

A type class abstracting over the product and compose operations of type classes over types of kind * -> *.

It serves as a replacement for the various Product* classes in scalaz.

Multiplication of instances is done via wrappers which are unpacked automatically if the implicits of scalaz.syntax.typelevel.TypeClasses are imported.

  3. abstract def compose[F[_], T <: TCList](FOuter: C[F], FInner: C[compose.T.Composed]): C[[α]F[compose.T.Composed[α]]]

    Given a type class instance for F, and a type class instance for a composition, produce a type class instance for the composition wrapped by F.

    Given a type class instance for F, and a type class instance for a composition, produce a type class instance for the composition wrapped by F.

    Note

    Users of this class should start with idCompose and use the functions on scalaz.typelevel.KTypeClass.WrappedComposition, which greatly improves type inference.

  4. abstract def product[F[_], T <: TCList](FHead: C[F], FTail: C[product.T.Product]): C[[α]GenericCons[[+X]X, F[α], product.T.Product[α]]]

    Given a type class instance for F, and a type class instance for a product, produce a type class instance for the product prepended with F.

    Given a type class instance for F, and a type class instance for a product, produce a type class instance for the product prepended with F.

    Note

    Users of this class should start with emptyProduct and use the functions on scalaz.typelevel.KTypeClass.WrappedProduct, which greatly improves type inference.
