This method does NOT return all snapshots. Its implementation deliberately returns a single page of results for any one call. It will return a single page based on the current or provided filters, updating the filters with the marker for the next page. Calling this repeatedly will iterate through pages. See the implementation of each for an example of such iteration.

It is arguably incorrect for the method not to return all snapshots, particularly considering the implementation in the corresponding ‘elb’ files. But this implementation has been released, and backwards-compatibility requires leaving it as implemented.

This will execute a block for each snapshot, fetching new pages of snapshots as required.
