Implementations

impl QDns

pub fn make_empty( resolvers: Option<Arc<ResolveConfig>>, opts: QuerySetup, ) -> CDnsResult<Self>

Initializes new empty storage for requests.

Arguments

• resolvers - an Arc ResolveConfig which contains configuration i.e nameservers

• opts - QuerySetup additional options or overrides. Use default() for default values.

Returns

Never panics. Returns Self.

pub fn add_request(&mut self, qtype: QType, req_name: impl Into<QDnsName>)

Adds new request to previously created empty storage for request with QDns::make_empty.

Arguemnts

• qtype - a QType type of the request

• req_name - a Into QDnsName which is target. i.e ‘localhost’ or ‘domain.tld’

Returns

• CDnsResult - Ok with nothing in inner type

• CDnsResult - Err with error description

pub fn make_a_aaaa_request( resolvers_opt: Option<Arc<ResolveConfig>>, req_name: impl Into<QDnsName>, opts: QuerySetup, ) -> CDnsResult<Self>

This is helper which makes for you an A, AAAA query. The order of A and AAAA and which from both are allowed is defined in the ResolveConfig.

Use this function directly. Do not use QDns::make_empty

Arguments

• resolvers - an Option value Arc ResolveConfig which can be used to override the system’s resolv.conf

• req_name - a Into QDnsName which is target i.e ‘localhost’ or ‘domain.tld’

• opts - QuerySetup additional options or overrides. Use default() for default values.

Returns

A CDnsResult is returned;

• Result::Ok - with Self as inner type

• Result::Err - with error description

pub fn query(self) -> QDnsQueryResult

Resolves the created query/ies.

Returns

• CDnsResult with QDnsQueryResult which may contain results

• CDnsResult with error

Should not panic. MT-safe.
