Enum AuthLookup 

#[non_exhaustive]
pub enum AuthLookup {
    Empty,
    Records {
        answers: LookupRecords,
        additionals: Option<LookupRecords>,
    },
    Resolved(Lookup),
    Response(Message),
}

The result of a lookup on a ZoneHandler

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Empty

No records

Records

Records

Fields

answers: LookupRecords

Authoritative answers

additionals: Option<LookupRecords>

Optional set of LookupRecords

Resolved(Lookup)

Available on crate feature resolver only.

Records resulting from a resolver lookup

Response(Message)

A response message

Implementations

impl AuthLookup

pub fn answers( answers: LookupRecords, additionals: Option<LookupRecords>, ) -> Self

Construct an answer with additional section

pub fn is_empty(&self) -> bool

Returns true if either the associated Records are empty, or this is a NameExists or NxDomain

pub fn was_empty(&self) -> bool

This is an NxDomain or NameExists, and has no associated records

this consumes the iterator, and verifies it is empty

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

Conversion to an iterator

pub fn unwrap_records(self) -> LookupRecords

Does not panic, but will return no records if it is not of that type

pub fn authorities(&self) -> Option<LookupRecordsIter<'_>>

Iterates over the records from the Authority section, if present.

pub fn additionals(&self) -> Option<LookupRecordsIter<'_>>

Iterates over the records from the Additional section, if present.

pub fn take_additionals(&mut self) -> Option<LookupRecords>

Takes the additional records, leaving behind None

Trait Implementations

impl Debug for AuthLookup

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

Formats the value using the given formatter.

impl Default for AuthLookup

fn default() -> AuthLookup

Returns the “default value” for a type.

impl From<Lookup> for AuthLookup

Available on crate feature resolver only.

fn from(lookup: Lookup) -> Self

Converts to this type from the input type.

impl From<LookupRecords> for AuthLookup

fn from(lookup: LookupRecords) -> Self

Converts to this type from the input type.

impl<'a> IntoIterator for &'a AuthLookup

type Item = &'a Record

The type of the elements being iterated over.

type IntoIter = AuthLookupIter<'a>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
