Struct domain::base::opt::chain::Chain

source ·
pub struct Chain<Name: ?Sized> { /* private fields */ }
Expand description

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§

source§

impl<Name: ?Sized> Chain<Name>

source

pub fn new(start: Name) -> Self
where Name: Sized,

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

source

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

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

source

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.

source

pub fn into_start(self) -> Name
where Name: Sized,

Converts the value into the start point.

impl<Octs> Chain<Dname<Octs>>

source

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.
