fn strip_loopback_endpoints(
path: Vec<OffchainPublicKey>,
me: &OffchainPublicKey,
) -> Vec<OffchainPublicKey>Expand description
Strip the leading source and trailing destination from a loopback path.
simple_loopback_to_self returns [me, intermediates..., me]. The caller
adds me as the destination and the planner prepends me as source, so
only the interior intermediate nodes are needed.
