Struct Chain

pub struct Chain<Name: ?Sized> { /* private fields */ }

Option data for the CHAIN option.

The CHAIN option can be used to request that the queried include all the records necessary to validate the DNSSEC signatures of an answer. The option includes the absolute domain name that serves as the starting point of the included records, i.e., the suffix of the queried name furthest away from the root to which the requesting resolver already has all necessary records.

Implementations

impl<Name: ?Sized> Chain<Name>

pub fn new(start: Name) -> Self

where Name: Sized,

Creates new CHAIN option data using the given name as the start.

pub fn new_ref(start: &Name) -> &Self

Creates a reference to CHAIN option data from a reference to the start.

pub fn start(&self) -> &Name

Returns a reference to the start point.

The start point is the name furthest along the chain to which the requester already has all necessary records.

pub fn into_start(self) -> Name

where Name: Sized,

Converts the value into the start point.

impl<Octs> Chain<Name<Octs>>

pub fn parse<'a, Src: Octets<Range<'a> = Octs> + ?Sized>( parser: &mut Parser<'a, Src>, ) -> Result<Self, ParseError>

Parses CHAIN option data from its wire format.

impl<Name: Hash> Hash for Chain<Name>

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.

where Name: OctetsFrom<SrcName>,

type Error = <Name as OctetsFrom<SrcName>>::Error

fn try_octets_from(src: Chain<SrcName>) -> Result<Self, Self::Error>

impl<Name> OptData for Chain<Name>

fn code(&self) -> OptionCode

Returns the option code associated with this option.

impl<Name: ToName> Ord for Chain<Name>

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

impl<Name, OtherName> PartialEq<Chain<OtherName>> for Chain<Name>

where Name: ToName, OtherName: ToName,

fn eq(&self, other: &Chain<OtherName>) -> 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.

impl<Name, OtherName> PartialOrd<Chain<OtherName>> for Chain<Name>

where Name: ToName, OtherName: ToName,

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

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.
