Struct MonitoringProxy

pub struct MonitoringProxy<'c>(/* private fields */);

Proxy for the org.freedesktop.DBus.Monitoring interface.

Implementations

impl<'c> MonitoringProxy<'c>

pub async fn new(conn: &Connection) -> Result<MonitoringProxy<'c>>

Creates a new proxy with the default service and path.

pub fn builder(conn: &Connection) -> ProxyBuilder<'c, Self>

Returns a customizable builder for this proxy.

pub fn into_inner(self) -> Proxy<'c>

Consumes self, returning the underlying zbus::Proxy.

pub fn inner(&self) -> &Proxy<'c>

The reference to the underlying zbus::Proxy.

pub async fn become_monitor(&self, n1: &[&str], n2: u32) -> Result<()>

Converts the connection into a monitor connection which can be used as a debugging/monitoring tool.

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

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>

Introspect the associated object, and return the XML description.

See the xml or quick_xml module for parsing the result.

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

where T: TryFrom<OwnedValue>, T::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>

where T: TryFrom<OwnedValue>, T::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<()>

where T: Into<Value<'t>> + '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<Arc<Message>>

where M: TryInto<MemberName<'m>>, 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>

where M: TryInto<MemberName<'m>>, 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.

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

where M: TryInto<MemberName<'m>>, 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

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

where M: TryInto<MemberName<'m>>, 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>>

where M: TryInto<MemberName<'m>>, 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>>

where M: TryInto<MemberName<'m>>, 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>>

Create a stream for all signals emitted by this service.

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

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<'_>>

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.
