Byte Size

ByteCount is an opaque Long value, used to indicate something like "File size" or "memory allocation", whatever is counted in bytes

EnumCompanion is a type to be extended by all enum companion objects to integrate them with Scalqa containers.

This is a recommended step, which might not be nessesasy in simple cases

 enum Direction:
   case Up,Down,Left,Right

 object Direction extends EnumCompanion[Direction]

 Direction.stream.tp

 // Output
 Stream(Up, Down, Left, Right)

Percent is an opaque Double value

Percent can be created with method constructors on primitives

 3.Percent.tp     // Prints: 3.0%
 3.14.Percent.tp  // Prints: 3.14%

Bi-Directional Function

TwoWayFunction allows to convert value to some type and back

It is used in two way binded collections

  val intToChar: TwoWayFunction[Int,Char] = TwoWayFunction(i => ('A' + i).toChar, _ - 'A')

  val list:  Idx.M[Int] = Stream(0, 2, 4).toBuffer
  val view:  Idx.M[Char] = list.mutableMapView(intToChar)

  list.stream.tp     // Prints Stream(0, 2, 4)
  view.stream.tp     // Prints Stream(A, C, E)

  view(1) = 'Z' // Note, only second collection is updated, but both are changed

  list.stream.tp     // Prints Stream(0, 25, 4)
  view.stream.tp     // Prints Stream(A, Z, E)
