trait HKTag[T] extends AnyTag

Internal unsafe API representing a poly-kinded, higher-kinded type tag.

To create a Tag* implicit for an arbitrary kind use the following syntax:

type TagK5[K[_, _, _, _, _]] = HKTag[ { type Arg[A, B, C, D, E] = K[A, B, C, D, E] } ]

As an argument to HKTag, you should specify the type variables your type parameter will take and apply them to it, in order.

type TagFGC[K[_[_, _], _[_], _[_[_], _, _, _]] = HKTag[ { type Arg[A[_, _], B[_], C[_[_], _, _, _]] = K[A, B, C] } ]

A convenience macro Tag.auto.T is available to automatically create a type lambda for a type of any kind:

def x[K[_[_, _], _[_], _[_[_], _, _, _]: Tag.auto.T]: Tag.auto.T[K] = implicitly[Tag.auto.T[K]]

Abstract Value Members

  1. abstract def closestClass: Class[_]

    Closest class found for the type or for a LUB of all intersection members in case of an intersection type.

    Closest class found for the type or for a LUB of all intersection members in case of an intersection type.

    A Scala type may not have an associated JVM class, as such this class may not be sufficient to create instances of T

    Only if tag.hasPreciseClass returns true it may be safe to reflect on closestClass
