o  FAMILY, 2 octets, indicates the family of the address contained in
   the option, using address family codes as assigned by IANA in
   Address Family Numbers [Address_Family_Numbers].
o  SOURCE PREFIX-LENGTH, an unsigned octet representing the leftmost
   number of significant bits of ADDRESS to be used for the lookup.
   In responses, it mirrors the same value as in the queries.
o  SCOPE PREFIX-LENGTH, an unsigned octet representing the leftmost
   number of significant bits of ADDRESS that the response covers.
   In queries, it MUST be set to 0.
o  ADDRESS, variable number of octets, contains either an IPv4 or
   IPv6 address, depending on FAMILY, which MUST be truncated to the
   number of bits indicated by the SOURCE PREFIX-LENGTH field,
   padding with 0 bits to pad to the end of the last octet needed.
o  A server receiving an ECS option that uses either too few or too
   many ADDRESS octets, or that has non-zero ADDRESS bits set beyond
   SOURCE PREFIX-LENGTH, SHOULD return FORMERR to reject the packet,
   as a signal to the software developer making the request to fix
   their implementation.

impl From<IpNet> for ClientSubnet

fn from(net: IpNet) -> Self

Converts to this type from the input type.

impl FromStr for ClientSubnet

type Err = AddrParseError
