pub fn read_peer_bytes(node: &NodeProto) -> Option<&[u8]>Expand description
Read the destination peer’s multihash bytes from a Send / gate
NodeProto. Returns None if the attribute is absent or carries
no byte content. The byte payload lives on attribute.s per the
ONNX convention for raw bytes (paired with
AttributeType::String); callers reconstruct the PeerId via
PeerId::from_bytes(read_peer_bytes(node)?).
