Struct Resolver 

pub struct Resolver {
    pub ns: Vec<SocketAddr>,
    pub tcp: bool,
    pub timeout: Option<Duration>,
}

An asynchronous DNS resolver.

Fields

ns: Vec<SocketAddr>

tcp: bool

timeout: Option<Duration>

Implementations

impl Resolver

pub fn new(ns: Vec<SocketAddr>) -> Resolver

pub fn empty() -> Resolver

Build a resolver with no nameservers

pub fn cloudflare() -> Resolver

Creates a new resolver using the CloudFlare Authoritative DNS service.

pub fn google() -> Resolver

Creates a new resolver using the Google Public DNS service.

pub fn from_system() -> Result<Resolver>

Creates a new resolver from /etc/resolv.conf.

pub fn from_system_v4() -> Result<Resolver>

Creates a new resolver from /etc/resolv.conf.

pub fn timeout(&mut self, timeout: Option<Duration>)

Sets a timeout within which each DNS query must complete.

Default setting is no timeout.

Trait Implementations

impl Clone for Resolver

fn clone(&self) -> Resolver

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Resolver

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

Formats the value using the given formatter.

impl Default for Resolver

fn default() -> Resolver

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Resolver

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl DnsResolver for Resolver

fn resolve(&self, name: &str, query_type: RecordType) -> Resolving

impl PartialEq for Resolver

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

Tests for self and other values to be equal, and is used by ==.

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 Serialize for Resolver

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
