I'm surprised, I find Go's doc generator to be very rudimentary. For example, you can't find the implementations of an interface, and given that interfaces are used often I have to resort to grepping the code to see what it means.

yes, it is easy, `for value in &set {}`. Not sure why you went all the way down to `Cycle`

In this case I agree that perhaps rustdoc should note that a full description should be alluded to (the full description of Cycle is on the Iterator trait's docs), but it's still IMO much better than go
