Anything I can do to exclude a particular field from data class .toString() except overriding it? I have a LAZY collection in a data class, so it throws an exception on .toString()

[Adam Powell]

Is a data class appropriate for this use case then? Would .equals or .hashCode accessing that lazy collection cause similar problems?

data classes by default use primary constructor parameters for toString, hashCode, and equals. You could use

fun foo() = (1..10).random()
data class D(val a: Int) {
    val b: Int by lazy { foo() }
}
val d1 = D(33)
println("d1 is $d1 and d1.b is ${d1.b}")
val d2 = D(33)
println("d2.b is ${d2.b} and d1 and d2 are equal: ${d1 == d2}")

which printed for me:
d1 is D(a=33) and d1.b is 9
d2.b is 6 and d1 and d2 are equal: true
