["Request"] min and max methods for NonEmptyList

[dorians]

What version are you currently using?

1.0.1

What would you like to see?

Kotlin's Iterable has methods minOrNull and maxOrNull:

listOf(1, 2, 3, 4, 5).minOrNull() // 1
listOf(1, 2, 3, 4, 5).maxOrNull() // 5

As a input list can be empty, they return nullable type:

emptyList<Int>().minOrNull() // null

I would be useful to have similar methods for NonEmptyList that return non-nullable values:

fun <T> NonEmptyList<T>.min(): T
fun <T> NonEmptyList<T>.max(): T

Other related methods:

• minByOrNull
• maxByOrNull

Hey @dorians,

That'd be great! I think that method should be restricted to Comparable<T>, no?

fun <T : Comparable<T>> NonEmptyList<T>.min(): T
fun <T : Comparable<T>> NonEmptyList<T>.max(): T

If you're interested we'd love the contribution!

@nomisRev yes, you're correct! I'll create PR for this one
