Struct async_std_resolver::lookup::Lookup

source · [−]

pub struct Lookup { /* private fields */ }

Expand description

Result of a DNS query when querying for any record type supported by the Trust-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) -> Lookup

Return new instance with given rdata and the maximum TTL.

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

Return new instance with given records and the maximum TTL.

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

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<'_>ⓘNotable traits for LookupIter<'a>`impl<'a> Iterator for LookupIter<'a> type Item = &'a RData;`

Returns a borrowed iterator of the returned IPs

pub fn record_iter(&self) -> LookupRecordIter<'_>ⓘNotable traits for LookupRecordIter<'a>`impl<'a> Iterator for LookupRecordIter<'a> type Item = &'a Record;`

Returns a borrowed iterator of the returned IPs

pub fn valid_until(&self) -> Instant

Returns the Instant at which this Lookup is no longer valid.

impl IntoIterator for Lookup

fn into_iter(self) -> <Lookup as IntoIterator>::IntoIter

This is most likely not a free conversion, the RDatas will be cloned if data is held behind an Arc with more than one reference (which is most likely the case coming from cache)
