where:
SOA records cause no additional section processing.
All times are in units of seconds.
Most of these fields are pertinent only for name server maintenance
operations. However, MINIMUM is used in all query operations that
retrieve RRs from a zone. Whenever a RR is sent in a response to a
query, the TTL field is set to the maximum of the TTL field from the RR
and the MINIMUM field in the appropriate SOA. Thus MINIMUM is a lower
bound on the TTL field for all RRs in a zone. Note that this use of
MINIMUM should occur when the RRs are copied into the response and not
when the zone is loaded from a master file or via a zone transfer. The
reason for this provison is to allow future dynamic update facilities to
change the SOA RR with known semantics.
Implementations
impl SOA
[src]
pub fn new(
mname: Name,
rname: Name,
serial: u32,
refresh: i32,
retry: i32,
expire: i32,
minimum: u32
) -> Self
[src]
mname: Name,
rname: Name,
serial: u32,
refresh: i32,
retry: i32,
expire: i32,
minimum: u32
) -> Self
Creates a new SOA record data.
Arguments
mname
- the name of the master, primary, authority for this zone.rname
- the name of the responsible party for this zone, e.g. an email address.serial
- the serial number of the zone, used for caching purposes.refresh
- the amount of time to wait before a zone is resynched.retry
- the minimum period to wait if there is a failure during refresh.expire
- the time until this master is no longer authoritative for the zone.minimum
- no zone records should have time-to-live values less than this minimum.
Return value
The newly created SOA record data.
pub fn increment_serial(&mut self)
[src]
Increments the serial number by one
pub fn mname(&self) -> &Name
[src]
MNAME The <domain-name> of the name server that was the
original or primary source of data for this zone.
Return value
The domain-name
of the name server that was the original or primary source of data for
this zone, i.e. the master name server.
pub fn rname(&self) -> &Name
[src]
RNAME A <domain-name> which specifies the mailbox of the
person responsible for this zone.
Return value
A domain-name
which specifies the mailbox of the person responsible for this zone, i.e.
the responsible name.
pub fn serial(&self) -> u32
[src]
SERIAL The unsigned 32 bit version number of the original copy
of the zone. Zone transfers preserve this value. This
value wraps and should be compared using sequence space
arithmetic.
Return value
The unsigned 32 bit version number of the original copy of the zone. Zone transfers preserve this value. This value wraps and should be compared using sequence space arithmetic.
pub fn refresh(&self) -> i32
[src]
REFRESH A 32 bit time interval before the zone should be
refreshed.
Return value
A 32 bit time interval before the zone should be refreshed, in seconds.
pub fn retry(&self) -> i32
[src]
RETRY A 32 bit time interval that should elapse before a
failed refresh should be retried.
Return value
A 32 bit time interval that should elapse before a failed refresh should be retried, in seconds.
pub fn expire(&self) -> i32
[src]
EXPIRE A 32 bit time value that specifies the upper limit on
the time interval that can elapse before the zone is no
longer authoritative.
Return value
A 32 bit time value that specifies the upper limit on the time interval that can elapse before the zone is no longer authoritative, in seconds
pub fn minimum(&self) -> u32
[src]
MINIMUM The unsigned 32 bit minimum TTL field that should be
exported with any RR from this zone.
Return value
The unsigned 32 bit minimum TTL field that should be exported with any RR from this zone.
