pub struct PeerByStableId {
pub stable_id: StableNodeId,
}Expand description
Look up a peer by its control-assigned stable node id (Node::stable_id).
The lookup a caller holding an older Node snapshot uses to refresh it before acting
on it — notably the Taildrop send path (tailscale::Device::send_file), which must not
dial a peer this node has since flagged expired. None means the db holds no peer with
that id: either it has left the tailnet, or no netmap has arrived yet.
Answers immediately in both cases; unlike PeerByName it does not queue until the
first peer update. A caller that already holds a snapshot has one to fall back on, and
blocking a send behind a netmap that may never come would be worse than answering from
what is known.
