indexed

This struct takes two ranges, source and indices, and creates a view of source as if its elements were reordered according to indices. indices may include only a subset of the elements of source and may also repeat elements.

Source must be a random access range. The returned range will be bidirectional or random-access if Indices is bidirectional or random-access, respectively.
