CoevalLift

@implicitNotFound("Cannot find implicit value for CoevalLift[${F}].") trait CoevalLift[F[_]] extends FunctionK[[A] =>> Coeval[A], F]

A lawless type class that specifies conversions from Coeval to similar data types (i.e. pure, synchronous).

A lawless type class that specifies conversions from Coeval to similar data types (i.e. pure, synchronous).

This is nothing more than a cats.arrow.FunctionK.

Abstract methods

def apply[A](coeval: Coeval[A]): F[A]

Converts Coeval[A] into F[A].

Converts Coeval[A] into F[A].

The operation should preserve laziness if possible.

def or[H[_]](h: FunctionK[H, F]): FunctionK[[_] =>> EitherK[[A] =>> Coeval[A], H, _$6], F]

Composes two instances of FunctionK into a new FunctionK that transforms a cats.data.EitherK to a single functor.

Composes two instances of FunctionK into a new FunctionK that transforms a cats.data.EitherK to a single functor.

This transformation will be used to transform left F values while h will be used to transform right H values.
