Struct trust_dns_proto::xfer::retry_dns_handle::RetryDnsHandle

#[must_use = "queries can only be sent through a ClientHandle"]pub struct RetryDnsHandle<H> where
    H: DnsHandle + Unpin + Send,
    H::Error: RetryableError,  { /* fields omitted */ }

Can be used to reattempt a queries if they fail

note Current value of this is not clear, it may be removed

Implementations

impl<H> RetryDnsHandle<H> where
    H: DnsHandle + Unpin + Send,
    H::Error: RetryableError, 

pub fn new(handle: H, attempts: usize) -> Self

Creates a new Client handler for reattempting requests on failures.

Arguments

• handle - handle to the dns connection
• attempts - number of attempts before failing

Trait Implementations

impl<H: Clone> Clone for RetryDnsHandle<H> where
    H: DnsHandle + Unpin + Send,
    H::Error: RetryableError, 

fn clone(&self) -> RetryDnsHandle<H>

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<H> DnsHandle for RetryDnsHandle<H> where
    H: DnsHandle + Send + Unpin + 'static,
    H::Error: RetryableError, 

type Response = Pin<Box<dyn Future<Output = Result<DnsResponse, Self::Error>> + Send + Unpin>>

The associated response from the response future, this should resolve to the Response message

type Error = <H as DnsHandle>::Error

Error of the response, generally this will be ProtoError

fn send<R: Into<DnsRequest>>(&mut self, request: R) -> Self::Response

Send a message via the channel in the client

fn is_verifying_dnssec(&self) -> bool

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

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

A classic DNS query
