A function parameter will be invoked one time or not invoked at all.

A function parameter will be invoked one or more times.

A function parameter will be invoked exactly one time.

A function parameter is called in place, but it's unknown how many times it can be called.

Ensures that this value is not less than the specified minimumValue.

fun <T : Comparable<T>> T.coerceAtLeast(minimumValue: T): T

Ensures that this value is not greater than the specified maximumValue.

fun <T : Comparable<T>> T.coerceAtMost(maximumValue: T): T

Ensures that this value lies in the specified range minimumValue..maximumValue.

fun <T : Comparable<T>> T.coerceIn(
    minimumValue: T?, 
    maximumValue: T?
): T

Ensures that this value lies in the specified range.

fun <T : Comparable<T>> T.coerceIn(
    range: ClosedFloatingPointRange<T>
): T

fun <T : Comparable<T>> T.coerceIn(range: ClosedRange<T>): T

Creates a range from this Comparable value to the specified that value.

operator fun <T : Comparable<T>> T.rangeTo(
    that: T
): ClosedRange<T>
