Struct CDS

pub struct CDS(/* private fields */);

Available on crate feature dnssec only.

RRSIG is really a derivation of the original SIG record data. See SIG for more documentation

Methods from Deref<Target = DS>

pub fn key_tag(&self) -> u16

RFC 4034, DNSSEC Resource Records, March 2005

5.1.1.  The Key Tag Field

   The Key Tag field lists the key tag of the DNSKEY RR referred to by
   the DS record, in network byte order.

   The Key Tag used by the DS RR is identical to the Key Tag used by
   RRSIG RRs.  Appendix B describes how to compute a Key Tag.

pub fn algorithm(&self) -> Algorithm

RFC 4034, DNSSEC Resource Records, March 2005

5.1.2.  The Algorithm Field

   The Algorithm field lists the algorithm number of the DNSKEY RR
   referred to by the DS record.

   The algorithm number used by the DS RR is identical to the algorithm
   number used by RRSIG and DNSKEY RRs.  Appendix A.1 lists the
   algorithm number types.

pub fn digest_type(&self) -> DigestType

RFC 4034, DNSSEC Resource Records, March 2005

5.1.3.  The Digest Type Field

   The DS RR refers to a DNSKEY RR by including a digest of that DNSKEY
   RR.  The Digest Type field identifies the algorithm used to construct
   the digest.  Appendix A.2 lists the possible digest algorithm types.

pub fn digest(&self) -> &[u8]

RFC 4034, DNSSEC Resource Records, March 2005

5.1.4.  The Digest Field

   The DS record refers to a DNSKEY RR by including a digest of that
   DNSKEY RR.

   The digest is calculated by concatenating the canonical form of the
   fully qualified owner name of the DNSKEY RR with the DNSKEY RDATA,
   and then applying the digest algorithm.

     digest = digest_algorithm( DNSKEY owner name | DNSKEY RDATA);

      "|" denotes concatenation

     DNSKEY RDATA = Flags | Protocol | Algorithm | Public Key.

   The size of the digest may vary depending on the digest algorithm and
   DNSKEY RR size.  As of the time of this writing, the only defined
   digest algorithm is SHA-1, which produces a 20 octet digest.

pub fn covers(&self, name: &Name, key: &DNSKEY) -> Result<bool, ProtoError>

Available on crate features dnssec-openssl or dnssec-ring only.

Validates that a given DNSKEY is covered by the DS record.

Return

true if and only if the DNSKEY is covered by the DS record.

Trait Implementations

impl BinEncodable for CDS

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

Write the type to the stream

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

Returns the object in binary form

impl Clone for CDS

fn clone(&self) -> CDS

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CDS

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

Formats the value using the given formatter.

impl Deref for CDS

type Target = DS

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'de> Deserialize<'de> for CDS

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for CDS

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

Formats the value using the given formatter.

impl Hash for CDS

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 CDS

fn eq(&self, other: &CDS) -> 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 RecordData for CDS

fn try_from_rdata(data: RData) -> Result<Self, RData>

Attempts to convert to this RecordData from the RData type, if it is not the correct type the original is returned

fn try_borrow(data: &RData) -> Option<&Self>

Attempts to borrow this RecordData from the RData type, if it is not the correct type the original is returned

fn record_type(&self) -> RecordType

Get the associated RecordType for the RecordData

fn into_rdata(self) -> RData

Converts this RecordData into generic RecordData

fn is_update(&self) -> bool

RDLENGTH = 0

impl Serialize for CDS

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for CDS

impl StructuralPartialEq for CDS
