fn resolve_loopback_edges(
inner: &InnerGraph,
me_idx: NodeIndex,
path_bytes: &[u8],
) -> Option<Vec<EdgeIndex>>Expand description
Resolves a loopback path from serialized node-index bytes into a validated chain of edge indices.
The path_bytes encode a PathId where each u64 is a NodeIndex.
The path is expected to start and end at me_idx (a closed loop).
Walks consecutive node pairs, finding the connecting edge for each.
Stops when the loop closes back to me_idx or when no edge exists
between a pair. Returns None if the path bytes have wrong length,
the first node is not me_idx, or fewer than 2 edges can be resolved.
