doesn't support records?

As far as I can tell, this doesn't support records? Is that correct?

I could only manage half a workaround; by using a custom "record" shape, and a manually encoded node label (e.g., <f0> a|<f1> b|<f2> c)) I could handle the nodes, but I can't figure out any way to get it to write edges as "node":f0 -> "node":f1 or node:f0 -> node:f1.

As far as the api goes, edge .From and .To just need to accept optional ports, and nodes need to accept a list of port names and labels (that can be nested in complicated ways, to be fair; they can be grouped in order to switch between horizontal fields and vertical fields).

you don't really need Record-nodes, but the HTML-layout in nodes will do all the work (and more). HTML-nodes can have many HTML-children, with "Port" attributes, so that edges will point from port to port precisely.
this is the specification: https://graphviz.org/doc/info/shapes.html
i tried to implement something like that here, but for the old version, now it's changed alot:
