I'm a bit worried these could go out of sync, but doc comments which would at least appear in most author IDEs could help with that if there's no better way (which I can't think of right now). Unfortunately, single fields cannot be made externally immutable in Rust. I'm sure others might have some experience here. :)

Oh oops I meant to make them doc comments, thanks. And yea those were exactly my thoughts, at the moment I can't think of a way to cache without risking them going out of sync, hoping this would have the least friction for keeping them in sync.

We could make their_node_id a tuple (PublicKey, NodeId), that way you're forced to update them in tandem.

Doesn't avoid the possibility of a mismatch but better than two fields.

This is done to avoid redundantly serializing peer node ids when forwarding gossip messages in `PeerManager::forward_broadcast_msg`.
