Durations

The range constraints of lengths of time, for both kotlin.time.Duration, with arguments such as 15.minutes, and java.time.Duration, with arguments such as Duration.ofDays(1).

A null argument checks nothing. A rule that reads a value that may be missing, such as max(customer.limit), never fails because of it: required on that value reports it once.

Meeting.kt

data class Meeting(
    val length: Duration?,
    val reminderBefore: java.time.Duration?
) : Validatable {
    override fun validation() = validation {
        ::length required { between(min = 15.minutes, max = 4.hours) }
        ::reminderBefore required { max(java.time.Duration.ofDays(1)) }
    }
}

Constraint	Checks
`min`	Is at least `min`.
`max`	Is at most `max`.
`greaterThan`	Is greater than `other`.
`lessThan`	Is less than `other`.
`between`	Is between `min` and `max`, both included.

`min`

min(min) on kotlin.time.Duration, java.time.Duration Checks that the duration is at least min. min

`max`

max(max) on kotlin.time.Duration, java.time.Duration Checks that the duration is at most max. max

`greaterThan`

greaterThan(other) on kotlin.time.Duration, java.time.Duration Checks that the duration is greater than other. greaterThan

`lessThan`

lessThan(other) on kotlin.time.Duration, java.time.Duration Checks that the duration is less than other. lessThan

`between`

between(min, max) on kotlin.time.Duration, java.time.Duration Checks that the duration is between min and max, both included. between
