Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

Subnet(ClientSubnet)

§

Unknown(u16, Vec<u8>)

Unknown, used to deal with unknown or unsupported codes
