Related Posts Loop

Hi,

Is there a way to loop thru related posts for a post – something like:

$loop = st_get_related_posts(….);
if ($loop->have_posts(){
while ( $loop->have_posts() ) {
$loop->the_post(); …..

I’m looking to code something myself rather than use the built-in widget.
Docs have st_related_posts, but unlike others I don’t see a ‘get’ equivalent.

Thanks
