Struct async_std_resolver::config::ResolverConfig

pub struct ResolverConfig { /* private fields */ }

Configuration for the upstream nameservers to use for resolution

Implementations

impl ResolverConfig

pub fn new() -> ResolverConfig

Creates a new empty configuration

pub fn google() -> ResolverConfig

Creates a default configuration, using 8.8.8.8, 8.8.4.4 and 2001:4860:4860::8888, 2001:4860:4860::8844 (thank you, Google).

Please see Google’s privacy statement for important information about what they track, many ISP’s track similar information in DNS. To use the system configuration see: Resolver::from_system_conf and AsyncResolver::from_system_conf

NameServerConfigGroups can be combined to use a set of different providers, see NameServerConfigGroup and ResolverConfig::from_parts

pub fn cloudflare() -> ResolverConfig

Creates a default configuration, using 1.1.1.1, 1.0.0.1 and 2606:4700:4700::1111, 2606:4700:4700::1001 (thank you, Cloudflare).

NameServerConfigGroups can be combined to use a set of different providers, see NameServerConfigGroup and ResolverConfig::from_parts

pub fn quad9() -> ResolverConfig

Creates a configuration, using 9.9.9.9, 149.112.112.112 and 2620:fe::fe, 2620:fe::fe:9, the “secure” variants of the quad9 settings (thank you, Quad9).

NameServerConfigGroups can be combined to use a set of different providers, see NameServerConfigGroup and ResolverConfig::from_parts

pub fn from_parts<G>(
    domain: Option<Name>,
    search: Vec<Name, Global>,
    name_servers: G
) -> ResolverConfig where
    G: Into<NameServerConfigGroup>, 

Create a ResolverConfig with all parts specified

Arguments

• domain - domain of the entity querying results. If the Name being looked up is not an FQDN, then this is the first part appended to attempt a lookup. ndots in the ResolverOption does take precedence over this.
• search - additional search domains that are attempted if the Name is not found in domain, defaults to vec![]
• name_servers - set of name servers to use for lookups, defaults are Google: 8.8.8.8, 8.8.4.4 and 2001:4860:4860::8888, 2001:4860:4860::8844

pub fn domain(&self) -> Option<&Name>

Returns the local domain

By default any names will be appended to all non-fully-qualified-domain names, and searched for after any ndots rules

pub fn set_domain(&mut self, domain: Name)

Set the domain of the entity querying results.

pub fn search(&self) -> &[Name]

Returns the search domains

These will be queried after any local domain and then in the order of the set of search domains

pub fn add_search(&mut self, search: Name)

Add a search domain

pub fn add_name_server(&mut self, name_server: NameServerConfig)

Add the configuration for a name server

pub fn name_servers(&self) -> &[NameServerConfig]

Returns a reference to the name servers

Trait Implementations

impl Clone for ResolverConfig

fn clone(&self) -> ResolverConfig

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

Performs copy-assignment from source.

impl Debug for ResolverConfig

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

Formats the value using the given formatter.

impl Default for ResolverConfig

fn default() -> ResolverConfig

Creates a default configuration, using 8.8.8.8, 8.8.4.4 and 2001:4860:4860::8888, 2001:4860:4860::8844 (thank you, Google).
