Use

IndexMaskMemory memory;
IndexMask selected_curves = ed::curves::retrieve_selected_curves(curves, memory);

(you'll have to make retrieve_selected_curves non-static and declare it in the ED_curves.hh header).

Use ``` IndexMaskMemory memory; IndexMask selected_curves = ed::curves::retrieve_selected_curves(curves, memory); ``` (you'll have to make `retrieve_selected_curves` non-static and declare it in the `ED_curves.hh` header).

With the change above, you can now do:

selected_curves.foreach_index([&](GrainSize(512), [&](const int curve_index) {
   materials.span[curve_index] = material_index;
});
With the change above, you can now do: ``` selected_curves.foreach_index([&](GrainSize(512), [&](const int curve_index) { materials.span[curve_index] = material_index; }); ```
