Struct ashpd::desktop::network_monitor::NetworkMonitor

pub struct NetworkMonitor<'a>(/* private fields */);

The interface provides network status information to sandboxed applications.

It is not a portal in the strict sense, since it does not involve user interaction. Applications are expected to use this interface indirectly, via a library API such as the GLib gio::NetworkMonitor interface.

Wrapper of the DBus interface: org.freedesktop.portal.NetworkMonitor.

Implementations

impl<'a> NetworkMonitor<'a>

pub async fn new() -> Result<NetworkMonitor<'a>, Error>

Create a new instance of NetworkMonitor.

pub async fn can_reach(&self, hostname: &str, port: u32) -> Result<bool, Error>

Returns whether the given hostname is believed to be reachable.

Arguments

• hostname - The hostname to reach.
• port - The port to reach.

Required version

The method requires the 3nd version implementation of the portal and would fail with Error::RequiresVersion otherwise.

Specifications

See also CanReach.

pub async fn is_available(&self) -> Result<bool, Error>

Returns whether the network is considered available. That is, whether the system as a default route for at least one of IPv4 or IPv6.

Required version

The method requires the 2nd version implementation of the portal and would fail with Error::RequiresVersion otherwise.

Specifications

See also GetAvailable.

pub async fn connectivity(&self) -> Result<Connectivity, Error>

Returns more detailed information about the host’s network connectivity.

Required version

The method requires the 2nd version implementation of the portal and would fail with Error::RequiresVersion otherwise.

Specifications

See also GetConnectivity.

pub async fn is_metered(&self) -> Result<bool, Error>

Returns whether the network is considered metered. That is, whether the system as traffic flowing through the default connection that is subject to limitations by service providers.

Required version

The method requires the 2nd version implementation of the portal and would fail with Error::RequiresVersion otherwise.

Specifications

See also GetMetered.

pub async fn status(&self) -> Result<NetworkStatus, Error>

Returns the three values all at once.

Required version

The method requires the 3nd version implementation of the portal and would fail with Error::RequiresVersion otherwise.

Specifications

See also GetStatus.

pub async fn receive_changed(&self) -> Result<impl Stream<Item = ()>, Error>

Emitted when the network configuration changes.

Specifications

See also changed.

Methods from Deref<Target = Proxy<'a>>

pub fn connection(&self) -> &Connection

Get a reference to the associated connection.

pub fn destination(&self) -> &BusName<'_>

Get a reference to the destination service name.

pub fn path(&self) -> &ObjectPath<'_>

Get a reference to the object path.

pub fn interface(&self) -> &InterfaceName<'_>

Get a reference to the interface.

pub async fn introspect(&self) -> Result<String, Error>

Introspect the associated object, and return the XML description.

See the xml module for parsing the result.

pub fn cached_property<T>( &self, property_name: &str ) -> Result<Option<T>, Error>

where T: TryFrom<OwnedValue>, <T as TryFrom<OwnedValue>>::Error: Into<Error>,

Get the cached value of the property property_name.

This returns None if the property is not in the cache. This could be because the cache was invalidated by an update, because caching was disabled for this property or proxy, or because the cache has not yet been populated. Use get_property to fetch the value from the peer.

pub fn cached_property_raw<'p>( &'p self, property_name: &'p str ) -> Option<impl Deref<Target = Value<'static>> + 'p>

Get the cached value of the property property_name.

Same as cached_property, but gives you access to the raw value stored in the cache. This is useful if you want to avoid allocations and cloning.

pub async fn get_property<T>(&self, property_name: &str) -> Result<T, Error>

where T: TryFrom<OwnedValue>, <T as TryFrom<OwnedValue>>::Error: Into<Error>,

Get the property property_name.

Get the property value from the cache (if caching is enabled) or call the Get method of the org.freedesktop.DBus.Properties interface.

pub async fn set_property<'t, T>( &self, property_name: &str, value: T ) -> Result<(), Error>

where T: 't + Into<Value<'t>>,

Set the property property_name.

Effectively, call the Set method of the org.freedesktop.DBus.Properties interface.

pub async fn call_method<'m, M, B>( &self, method_name: M, body: &B ) -> Result<Message, Error>

where M: TryInto<MemberName<'m>>, <M as TryInto<MemberName<'m>>>::Error: Into<Error>, B: Serialize + DynamicType,

Call a method and return the reply.

Typically, you would want to use call method instead. Use this method if you need to deserialize the reply message manually (this way, you can avoid the memory allocation/copying, by deserializing the reply to an unowned type).

pub async fn call<'m, M, B, R>( &self, method_name: M, body: &B ) -> Result<R, Error>

where M: TryInto<MemberName<'m>>, <M as TryInto<MemberName<'m>>>::Error: Into<Error>, B: Serialize + DynamicType, R: for<'d> DynamicDeserialize<'d>,

Call a method and return the reply body.

Use call_method instead if you need to deserialize the reply manually/separately.

pub async fn call_with_flags<'m, M, B, R>( &self, method_name: M, flags: BitFlags<MethodFlags>, body: &B ) -> Result<Option<R>, Error>

where M: TryInto<MemberName<'m>>, <M as TryInto<MemberName<'m>>>::Error: Into<Error>, B: Serialize + DynamicType, R: for<'d> DynamicDeserialize<'d>,

Call a method and return the reply body, optionally supplying a set of method flags to control the way the method call message is sent and handled.

Use call instead if you do not need any special handling via additional flags. If the NoReplyExpected flag is passed , this will return None immediately after sending the message, similar to call_noreply

pub async fn call_noreply<'m, M, B>( &self, method_name: M, body: &B ) -> Result<(), Error>

where M: TryInto<MemberName<'m>>, <M as TryInto<MemberName<'m>>>::Error: Into<Error>, B: Serialize + DynamicType,

Call a method without expecting a reply

This sets the NoReplyExpected flag on the calling message and does not wait for a reply.

pub async fn receive_signal<'m, M>( &self, signal_name: M ) -> Result<SignalStream<'m>, Error>

where M: TryInto<MemberName<'m>>, <M as TryInto<MemberName<'m>>>::Error: Into<Error>,

Create a stream for signal named signal_name.

pub async fn receive_signal_with_args<'m, M>( &self, signal_name: M, args: &[(u8, &str)] ) -> Result<SignalStream<'m>, Error>

where M: TryInto<MemberName<'m>>, <M as TryInto<MemberName<'m>>>::Error: Into<Error>,

Same as Proxy::receive_signal but with a filter.

The D-Bus specification allows you to filter signals by their arguments, which helps avoid a lot of unnecessary traffic and processing since the filter is run on the server side. Use this method where possible. Note that this filtering is limited to arguments of string types.

The arguments are passed as a tuples of argument index and expected value.

pub async fn receive_all_signals(&self) -> Result<SignalStream<'static>, Error>

Create a stream for all signals emitted by this service.

pub async fn receive_property_changed<'name, T>( &self, name: &'name str ) -> PropertyStream<'a, T>

where 'name: 'a,

Get a stream to receive property changed events.

Note that zbus doesn’t queue the updates. If the listener is slower than the receiver, it will only receive the last update.

If caching is not enabled on this proxy, the resulting stream will not return any events.

pub async fn receive_owner_changed( &self ) -> Result<OwnerChangedStream<'_>, Error>

Get a stream to receive destination owner changed events.

If the proxy destination is a unique name, the stream will be notified of the peer disconnection from the bus (with a None value).

If the proxy destination is a well-known name, the stream will be notified whenever the name owner is changed, either by a new peer being granted ownership (Some value) or when the name is released (with a None value).

Note that zbus doesn’t queue the updates. If the listener is slower than the receiver, it will only receive the last update.
