In a sense, data structures are "primitives" when it comes to implementation. Their structures and algorithms are published, and often there are numerous examples in other languages you can use to template your own Ruby code from. There seriously aren't any tips or exercises except to just translate from pseudocode into whatever language you want. You might be looking for something more specific - e.g. functional implementations - but there's nothing in your post to suggest that's what you want.
