Implementations

impl DnsNSec

pub fn new( name: &str, class: u16, ttl: u32, next_domain: String, type_bitmap: Vec<u8>, ) -> Self

pub fn types(&self) -> Vec<u16>

Returns the types marked by type_bitmap

Trait Implementations

impl Clone for DnsNSec

fn clone(&self) -> DnsNSec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DnsNSec

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

Formats the value using the given formatter.

impl DnsRecordExt for DnsNSec

fn get_record(&self) -> &DnsRecord

fn get_record_mut(&mut self) -> &mut DnsRecord

fn write(&self, packet: &mut DnsOutPacket)

fn any(&self) -> &dyn Any

fn matches(&self, other: &dyn DnsRecordExt) -> bool

Returns whether other record is considered the same except TTL.

fn rrdata_match(&self, other: &dyn DnsRecordExt) -> bool

Returns whether other record has the same rdata.

fn compare_rdata(&self, other: &dyn DnsRecordExt) -> Ordering

Returns the result based on a byte-level comparison of rdata. If other is not valid, returns Greater.

fn rdata_print(&self) -> String

Returns a human-readable string of rdata.

fn clone_box(&self) -> DnsRecordBox

fn compare(&self, other: &dyn DnsRecordExt) -> Ordering

Returns the result based on “lexicographically later” defined below.

fn get_class(&self) -> u16

Returns the class only, excluding class_flush / unique bit.

fn get_cache_flush(&self) -> bool

fn get_name(&self) -> &str

Return the new name if exists, otherwise the regular name in DnsEntry.

fn get_type(&self) -> RRType

fn reset_ttl(&mut self, other: &dyn DnsRecordExt)

Resets TTL using other record. self.refresh and self.expires are also reset.

fn get_created(&self) -> u64

fn get_expire(&self) -> u64

fn set_expire(&mut self, expire_at: u64)

fn set_expire_sooner(&mut self, expire_at: u64)

Set expire as expire_at if it is sooner than the current expire.

fn updated_refresh_time(&mut self, now: u64) -> Option<u64>

Given now, if the record is due to refresh, this method updates the refresh time and returns the new refresh time. Otherwise, returns None.

fn suppressed_by_answer(&self, other: &dyn DnsRecordExt) -> bool

Returns true if another record has matched content, and if its TTL is at least half of this record’s.

fn suppressed_by(&self, msg: &DnsIncoming) -> bool

Required by RFC 6762 Section 7.1: Known-Answer Suppression.
