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.

Implementations

impl ClientSubnet

pub fn new(address: IpAddr, source_prefix: u8, scope_prefix: u8) -> Self

Construct a new EcsOption with the address, source_prefix and scope_prefix.

pub fn len(&self) -> u16

Returns the length in bytes of the EdnsOption

pub fn is_empty(&self) -> bool

Returns true if the length in bytes of the EcsOption is 0

Trait Implementations

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

fn read(decoder: &mut BinDecoder<'a>) -> ProtoResult<Self>

Read the type from the stream

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

Returns the object in binary form

impl BinEncodable for ClientSubnet

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

Write the type to the stream

fn to_bytes(&self) -> ProtoResult<Vec<u8>>

Returns the object in binary form

impl Clone for ClientSubnet

fn clone(&self) -> ClientSubnet

Returns a copy 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

Formats the value using the given formatter.

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

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

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

impl Hash for ClientSubnet

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ClientSubnet

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

This method tests for self and other values to be equal, and is used by ==.

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

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

fn partial_cmp(&self, other: &ClientSubnet) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method 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

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