Struct gio::Resolver

#[repr(transparent)]
pub struct Resolver { /* private fields */ }

Resolver provides cancellable synchronous and asynchronous DNS resolution, for hostnames (ResolverExt::lookup_by_address(), ResolverExt::lookup_by_name() and their async variants) and SRV (service) records (ResolverExt::lookup_service()).

NetworkAddress and NetworkService provide wrappers around Resolver functionality that also implement SocketConnectable, making it easy to connect to a remote host/service.

This is an Abstract Base Class, you cannot instantiate it.

Signals

reload

Emitted when the resolver notices that the system resolver configuration has changed.

Implements

ResolverExt, glib::ObjectExt

Implementations

impl Resolver

pub const NONE: Option<&'static Resolver> = None

pub fn default() -> Resolver

Gets the default Resolver. You should unref it when you are done with it. Resolver may use its reference count as a hint about how many threads it should allocate for concurrent DNS resolutions.

Returns

the default Resolver.

Trait Implementations

impl Clone for Resolver

fn clone(&self) -> Self

Returns a copy 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 Display for Resolver

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

Formats the value using the given formatter.

impl HasParamSpec for Resolver

type ParamSpec = ParamSpecObject

type SetValue = Resolver

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str) -> ParamSpecObjectBuilder<'_, Resolver>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for Resolver

fn hash<H>(&self, state: &mut H)where H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Resolver

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl ParentClassIs for Resolver

type Parent = Object

impl<OT: ObjectType> PartialEq<OT> for Resolver

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl<OT: ObjectType> PartialOrd<OT> for Resolver

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl StaticType for Resolver

fn static_type() -> Type

Returns the type identifier of Self.
