inline operator fun IntRange.contains(element: Int?): Boolean(source)
inline operator fun LongRange.contains(element: Long?): Boolean(source)
inline operator fun CharRange.contains(element: Char?): Boolean(source)

Returns true if this range contains the specified element.

Always returns false if the element is null.
