final class EqualsDiffer[T](isIgnored: Boolean, valueToString: T => String) extends ValueDiffer[T]

Differ where the two values are compared by using the equals method. If the two values aren't equal, then we use the provided valueToString function to output the diagnostic output.

trait ValueDiffer[T] extends Differ[T]

Differ where the error diagnostic output is just string values. Simple types where a string representation is enough for diagnostics purposes should use Differ.useEquals (EqualsDiffer is a subtype of this trait). For example, Differ for Int, String, java.time.Instant are all ValueDiffers.

This trait also provide an extra contramap method which makes it easy to write instances for newtypes / opaque types.
