nit: this will have more attributes in the future, so it may be convenient to just use std::tie and grow the list as attributes are added, so something like:
`return std::tie(Attrs1.ResourceClass, Attrs1.IsROV, /*is_cube, is_ms, texture_dimension etc*/) == std::tie(Attrs2.ResourceClass, Attrs2.IsROV);
