fun IntRange.clamp(value: Int) = when {
    value <= start -> start
    value >= endInclusive -> endInclusive
    else -> value
}

coerceAtLeast

coerceAtMost

coerceIn

extensions on Int.

5.coerceIn(3..8) == 5
1.coerceIn(3..8) == 3
9.coerceIn(3..8) == 8

Exactly what I wanted, thanks!

I looked trough everything on

IntRange

, that would have been a better place to put in I think.

@Pavlo Liapota I think coercing is not so much a part of ints, it's more a function of ranges.

I see your point. But for me it is more clear when you call function on

Int

to get a new

Int

. It is like you call

filter

map

List

to get another

List

Fair point as well.

The intension here is to limit value of

Int

Range

is just nice structure to pass max and min value.

5.coerceIn(min, max)

exists as well. That makes sense then.

I really wanna make a library that allows you to delegate number declarations to ranges that constrain their value, e.g

val foo: Int by RestrictedInt(-2..5)

, but I ran into issues when I first started writing it and shelved it when other work came up. but here is the start...

Hmm, any reason you need a

RestrictedInteger

type and not all of it can be handled in the delegate? And what issue ls did you have?

I don't fully understand the question but I ran into an issue in the top level

compareTo()

functions, I think?
