pub fn to_peer_id(node_index: NodeIndex) -> Option<PeerId>Expand description
Convert an aleph-bft NodeIndex into a PeerId, if it can represent one.
NodeIndex wraps a usize and its decoder accepts any u64 verbatim, so
every index embedded in a message received from a peer is chosen by that
peer and may not correspond to any peer at all. Callers have to handle
None instead of panicking, since a panic in the consensus task shuts down
the entire node.
