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.

Trait Implementations

impl<'a> BinDecodable<'a> for ClientSubnet

fn read(decoder: &mut BinDecoder<'a>) -> Result<ClientSubnet, ProtoError>

Read the type from the stream

fn from_bytes(bytes: &'r [u8]) -> Result<Self, ProtoError>

Returns the object in binary form

impl BinEncodable for ClientSubnet

fn emit(&self, encoder: &mut BinEncoder<'_>) -> Result<(), ProtoError>

Write the type to the stream

fn to_bytes(&self) -> Result<Vec<u8>, ProtoError>

impl Clone for ClientSubnet

fn clone(&self) -> ClientSubnet

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ClientSubnet

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl From<IpNet> for ClientSubnet

fn from(net: IpNet) -> ClientSubnet

Converts to this type from the input type.

impl FromStr for ClientSubnet

type Err = AddrParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<ClientSubnet, <ClientSubnet as FromStr>::Err>

Parses a string s to return a value of this type.

impl Hash for ClientSubnet

impl PartialEq for ClientSubnet

fn eq(&self, other: &ClientSubnet) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<'a> TryFrom<&'a [u8]> for ClientSubnet

type Error = ProtoError

The type returned in the event of a conversion error.

fn try_from( value: &'a [u8], ) -> Result<ClientSubnet, <ClientSubnet as TryFrom<&'a [u8]>>::Error>

Performs the conversion.

impl<'a> TryFrom<&'a ClientSubnet> for Vec<u8>

type Error = ProtoError

The type returned in the event of a conversion error.

fn try_from( value: &'a ClientSubnet, ) -> Result<Vec<u8>, <Vec<u8> as TryFrom<&'a ClientSubnet>>::Error>

Performs the conversion.
