Lift the I
type member to a parameter.
Lift the I
type member to a parameter. It is usually more
convenient to use Aux
than a structural type.
See by
method.
Like lift(fa).contramap(_k)
.
Partial application of type parameters to apply
.
Partial application of type parameters to apply
. It is often
more convenient to invoke ContravariantCoyoneda.by[F]{x: X =>
...}
then ContravariantCoyoneda[...](...){x: X => ...}
.
ContravariantCoyoneda[F,_]
is a contravariant functor for any
F
.
ContravariantCoyoneda[F,_]
is a contravariant functor for any
F
.
F[A]
converts to ContravariantCoyoneda[F,A]
for any F
.
