Trait domain::resolv::resolver::Resolver [−][src]
A type that acts as a DNS resolver.
A resolver is anything that tries to answer questions using the DNS. The
query
method takes a single question and returns a future that will
eventually resolve into either an answer or an IO error.
Associated Types
type Octets: AsRef<[u8]>
[src]
type Answer: AsRef<Message<Self::Octets>>
[src]
The answer returned by a query.
This isn’t Message
directly as it may be useful for the resolver
to provide additional information. For instance, a validating
resolver (a resolver that checks whether DNSSEC signatures are
correct) can supply more information as to why validation failed.
type Query: Future<Output = Result<Self::Answer, Error>>
[src]
The future resolving into an answer.
Required methods
fn query<N, Q>(&self, question: Q) -> Self::Query where
N: ToDname,
Q: Into<Question<N>>,
[src]
N: ToDname,
Q: Into<Question<N>>,
Returns a future answering a question.
The method takes anything that can be converted into a question and produces a future trying to answer the question.
