type Range<T>

A range definition for any type of (orderable) value. If a start or end is defined, a tuple can be used where the second item is a boolean indicating whether that end is inclusive (true) or exclusive (false). A Range of type T can have one of the following forms:

  • { end: T }
  • { end: [T, boolean] }
  • { start: T }
  • { start: T, end: T }
  • { start: T, end: [T, boolean] }
  • { start: [T, boolean] }
  • { start: [T, boolean], end: T }
  • { start: [T, boolean], end: [T, boolean] }
