isNotIdenticalTo

fun <T> Validatable<T?>.isNotIdenticalTo(other: T?): Constraint

The validatable value must not be identical to other when this constraint is applied.

The values are considered not identical if they are not referentially equal.

Code example:

data object Foo
data object Bar

val validate = Validator<Any> { isNotIdenticalTo(Foo) }
validate(Bar) // Success
validate(Foo) // Failure (message: Must not be identical to "Foo")
