2.1.1.  The CSYNC Resource Record Wire Format

The CSYNC RDATA consists of the following fields:

Implementations§

source§

impl CSYNC

source

pub fn new( soa_serial: u32, immediate: bool, soa_minimum: bool, type_bit_maps: Vec<RecordType>, ) -> Self

Creates a new CSYNC record data.

§Arguments
  • soa_serial - A serial number for the zone
  • immediate - A flag signalling if the change should happen immediately
  • soa_minimum - A flag to used to signal if the soa_serial should be validated
  • type_bit_maps - a bit map of the types to synchronize
§Return value

The new CSYNC record data.

pub fn type_bit_maps(&self) -> &[RecordType]

RFC 7477, Child-to-Parent Synchronization in DNS, March 2015

2.1.1.2.1.  The Type Bit Map Field

   The Type Bit Map field indicates the record types to be processed by
   the parental agent, according to the procedures in Section 3.  The
   Type Bit Map field is encoded in the same way as the Type Bit Map
   field of the NSEC record, described in [RFC4034], Section 4.1.2.  If
   a bit has been set that a parental agent implementation does not
   understand, the parental agent MUST NOT act upon the record.
   Specifically, a parental agent must not simply copy the data, and it
   must understand the semantics associated with a bit in the Type Bit
   Map field that has been set to 1.
source

pub fn flags(&self) -> u16

RFC 7477, Child-to-Parent Synchronization in DNS, March 2015

2.1.1.2.  The Flags Field

   The Flags field contains 16 bits of boolean flags that define
   operations that affect the processing of the CSYNC record.  The flags
   defined in this document are as follows:

      0x00 0x01: "immediate"

      0x00 0x02: "soaminimum"

   The definitions for how the flags are to be used can be found in
   Section 3.

   The remaining flags are reserved for use by future specifications.
   Undefined flags MUST be set to 0 by CSYNC publishers.  Parental
   agents MUST NOT process a CSYNC record if it contains a 1 value for a
   flag that is unknown to or unsupported by the parental agent.
