Struct Resolver

pub struct Resolver { /* private fields */ }

The object that handles DNS resolution. Use default() to get the default resolver.

GResolver 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 GResolver functionality that also implement SocketConnectable, making it easy to connect to a remote host/service.

The default resolver (see default()) has a timeout of 30s set on it since GLib 2.78. Earlier versions of GLib did not support resolver timeouts.

This is an abstract type; subclasses of it implement different resolvers for different platforms and situations.

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

Properties

timeout

The timeout applied to all resolver lookups, in milliseconds.

This may be changed through the lifetime of the #GResolver. The new value will apply to any lookups started after the change, but not to any already-ongoing lookups.

If this is 0, no timeout is applied to lookups.

No timeout was applied to lookups before this property was added in GLib 2.78.

Readable | Writeable

Signals

reload

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

Implements

ResolverExt, [trait@glib::ObjectExt]

GLib type: GObject with reference counted clone semantics.

Implementations

impl Resolver

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

pub fn default() -> Resolver

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

Returns

the default #GResolver.

Trait Implementations

impl Clone for Resolver

fn clone(&self) -> Self

Makes a clone of this shared reference.

This increments the strong reference count of the object. Dropping the object will decrement it again.

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 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,

Hashes the memory address of this object.

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

Comparison for two GObjects.

Compares the memory addresses of the provided objects.

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,

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

Equality for two GObjects.

Two GObjects are equal if their memory addresses 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<OT: ObjectType> PartialOrd<OT> for Resolver

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

Partial comparison for two GObjects.

Compares the memory addresses of the provided objects.

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 StaticType for Resolver

fn static_type() -> Type

Returns the type identifier of Self.
