[HoledRange] Sequences and Transformations

HoledRange has reached v 0.1.3 with two additions:

  • Iterating over ranges (contributed by Hugo a.k.a. Zyigh)
  • Transforming ranges into other ranges
Transformations

Simple idea, full of tricks: how do I apply a function f to transform a domain?

  • It has to result to a possible bound value for the domain (ie Hashable & Comparable)
  • We need to check the ordering of the new values in case the transformation flips the sign (eg [0;1] -> [-1;0])
  • We need to optimize the storage as we go in case the transformation collapses holes
