final case class Equivalence[A, B](to: (A) => B, from: (B) => A) extends Product with Serializable

An Equivalence[A, B] defines an equivalence between two types A and B. These types represent different ways to store the same information.

For example, a List[Byte] is equivalent to a Vector[Byte]. Similarly, a List[Char] is equivalent to a String.

Equivalences are symmetrical. So if A is equivalent to B, then B is equivalent to A.

to

A function that converts an A into a B.

from

A function that converts a B into an A.
