Lookup

hickory_resolver::lookup

Struct Lookup

pub struct Lookup { /* private fields */ }

Expand description

Result of a DNS query when querying for any record type supported by the Hickory DNS Proto library.

For IP resolution see LookupIp, as it has more features for A and AAAA lookups.

Implementations§

impl Lookup

pub fn from_rdata(query: Query, rdata: RData) -> Self

Return new instance with given rdata and the maximum TTL.

pub fn new_with_max_ttl(query: Query, records: Arc<[Record]>) -> Self

Return new instance with given records and the maximum TTL.

pub fn new_with_deadline( query: Query, records: Arc<[Record]>, valid_until: Instant, ) -> Self

Return a new instance with the given records and deadline.

pub fn query(&self) -> &Query

Returns a reference to the Query that was used to produce this result.

pub fn iter(&self) -> LookupIter<'_> ⓘ

Returns an iterator over the data of all records returned during the query.

It may include additional record types beyond the queried type, e.g. CNAME.

pub fn record_iter(&self) -> LookupRecordIter<'_> ⓘ

Returns an iterator over all records returned during the query.

It may include additional record types beyond the queried type, e.g. CNAME.

pub fn valid_until(&self) -> Instant

Returns the Instant at which this Lookup is no longer valid.

pub fn records(&self) -> &[Record]

Returns an slice over all records that were returned during the query, this can include additional record types beyond the queried type, e.g. CNAME.

pub fn extend_records(&mut self, other: Vec<Record>)

Add new records to this lookup, without creating a new Lookup
