Function `std.range.Indexed.physicalIndex`

Returns the physical index into the source range corresponding to a given logical index. This is useful, for example, when indexing an Indexed without adding another layer of indirection.


						
				size_t physicalIndex
				(
				

				  size_t logicalIndex
				

				);

Example

auto ind = indexed([1, 2, 3, 4, 5], [1, 3, 4]);
writeln(ind.physicalIndex(0)); // 1
}
