Struct gio::Resolver

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.

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 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 Resolver. 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.

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) -> 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 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.
