Detailed Description

template<typename T>
struct blender::offset_indices::GroupedSpan< T >

References many separate spans in a larger contiguous array. This gives a more efficient way to store many grouped arrays, without requiring many small allocations, giving the general benefits of using contiguous memory.

Note: If the offsets are shared between many GroupedSpan objects, it will still be more efficient to retrieve the #IndexRange only once and slice each span.
