Struct hickory_resolver::name_server::NameServer

pub struct NameServer<P: ConnectionProvider> { /* private fields */ }

This struct is used to create DnsHandle with the help of P.

Implementations

impl<P> NameServer<P>

where P: ConnectionProvider + Send,

pub fn new( config: NameServerConfig, options: ResolverOpts, connection_provider: P, ) -> Self

Construct a new Nameserver with the configuration and options. The connection provider will create UDP and TCP sockets

pub fn trust_nx_responses(&self) -> bool

Specifies that this NameServer will treat negative responses as permanent failures and will not retry

Trait Implementations

impl<P: Clone + ConnectionProvider> Clone for NameServer<P>

where P::Conn: Clone,

fn clone(&self) -> NameServer<P>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<P> Debug for NameServer<P>

where P: ConnectionProvider + Send,

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

Formats the value using the given formatter.

impl<P> DnsHandle for NameServer<P>

where P: ConnectionProvider + Clone,

type Response = Pin<Box<dyn Stream<Item = Result<DnsResponse, ProtoError>> + Send>>

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

fn is_verifying_dnssec(&self) -> bool

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

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

Send a message via the channel in the client

fn is_using_edns(&self) -> bool

Allow for disabling EDNS

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

A classic DNS query

impl<P> Ord for NameServer<P>

where P: ConnectionProvider + Send,

fn cmp(&self, other: &Self) -> Ordering

Custom implementation of Ord for NameServer which incorporates the performance of the connection into it’s ranking

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl<P> PartialEq for NameServer<P>

where P: ConnectionProvider + Send,

fn eq(&self, other: &Self) -> bool

NameServers are equal if the config (connection information) are equal

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<P> PartialOrd for NameServer<P>

where P: ConnectionProvider + Send,

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<P> Eq for NameServer<P>

where P: ConnectionProvider + Send,
