Methods from Deref<Target = Proxy<'c>>§

source

pub fn connection(&self) -> &Connection

Get a reference to the associated connection.

source

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

Get a reference to the destination service name.

source

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

Get a reference to the object path.

source

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

Get a reference to the interface.

source

pub async fn introspect(&self) -> impl Future<Output = Result<String, Error>>

Introspect the associated object, and return the XML description.

See the xml or quick_xml module for parsing the result.

source

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.

source

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.

source

pub async fn get_property<T>( &self, property_name: &str ) -> impl Future<Output = 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.

source

pub async fn set_property<'t, T>( &self, property_name: &str, value: T ) -> impl Future<Output = 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.

source

pub async fn call_method<'m, M, B>( &self, method_name: M, body: &B ) -> impl Future<Output = Result<Arc<Message, Global>, 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).

source

pub async fn call<'m, M, B, R>( &self, method_name: M, body: &B ) -> impl Future<Output = Result<R, Error>>where M: TryInto<MemberName<'m>>, <M as TryInto<MemberName<'m>>>::Error: Into<Error>, B: Serialize + DynamicType, R: DeserializeOwned + Type,

Call a method and return the reply body.

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

source

pub async fn call_with_flags<'m, M, B, R>( &self, method_name: M, flags: BitFlags<MethodFlags, <MethodFlags as RawBitFlags>::Numeric>, body: &B ) -> impl Future<Output = Result<Option<R>, Error>>where M: TryInto<MemberName<'m>>, <M as TryInto<MemberName<'m>>>::Error: Into<Error>, B: Serialize + DynamicType, R: DeserializeOwned + Type,

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

source

pub async fn call_noreply<'m, M, B>( &self, method_name: M, body: &B ) -> impl Future<Output = 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.

source

pub async fn receive_signal<'m, M>( &self, signal_name: M ) -> impl Future<Output = 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.

source

pub async fn receive_signal_with_args<'m, M>( &self, signal_name: M, args: &[(u8, &str)] ) -> impl Future<Output = 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.

source

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

Create a stream for all signals emitted by this service.

source

pub async fn receive_property_changed<'name, T>( &self, name: &'name str ) -> impl Future<Output = 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.

source

pub async fn receive_owner_changed( &self ) -> impl Future<Output = 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.
