The Span class allows the creation of views over contiguous memory. The view do not own memory, is typed and has a length. It can be used as a replacement of the traditional pair of pointer and size in parameters or class fields. Main operations: - size(): return the lenght of the memory viewed - empty(): return if the memory viewed is empty - [index]: access elements viewed - data(): return a pointer to the memory viewed. - first(count): Create a subview from the first count elements. - last(count): Create a subview from the last count elements. - == and !=: compare two views or a view to array and return if they are equal or not. The Span class came in two flavors: - Static size: The size is encoded in the Span type and it is as lightweitgh as a single pointer, - Dynamic size: The object can store arbitrary views and it costs one pointer and the size of the view. |
