Expand description

A trait for implementing high level functions of DNS.

Required Associated Types§

type Response: Stream<Item = Result<DnsResponse, ProtoError>> + Send + Unpin + 'static

The associated response from the response stream, this should resolve to the Response messages

Required Methods§

fn send<R>(&self, request: R) -> Self::Response
where R: Into<DnsRequest> + Unpin + Send + 'static,

Send a message via the channel in the client

§Arguments
  • request - the fully constructed Message to send, note that most implementations of will most likely be required to rewrite the QueryId, do no rely on that as being stable.

Provided Methods§

fn is_verifying_dnssec(&self) -> bool

Only returns true if and only if this DNS handle is validating DNSSEC.

If the DnsHandle impl is wrapping other clients, then the correct option is to delegate the question to the wrapped client.

fn is_using_edns(&self) -> bool

Allow for disabling EDNS

fn lookup(&self, query: Query, options: DnsRequestOptions) -> Self::Response

A classic DNS query

This is identical to query, but instead takes a Query object.

§Arguments
  • query - the query to lookup
  • options - options to use when constructing the message

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
