[src]
conn: Connection,
destination: String,

[src]
Consumes self
, returning the underlying zbus::Proxy
.

pub async fn get(
&self,
interface_name: &str,
property_name: &str
) -> Result<OwnedValue>
[src]

interface_name: &str,
property_name: &str

[src]
H: FnMut(&str, HashMap<&str, Value<'_>>, Vec<&str>) -> BoxFuture<'static, Result<()>> + Send + 'static,

signal. This is a convenient wrapper around zbus::azync::Proxy::connect_signal
.

signal. This is a convenient wrapper around zbus::azync::Proxy::disconnect_signal
.
pub async fn introspect(&self) -> Result<String>
[src]
Methods from Deref<Target = Proxy<'c>>
pub fn connection(&self) -> &Connection
[src]
Get a reference to the associated connection.
pub fn destination(&self) -> &str
[src]
Get a reference to the destination service name.
pub fn path(&self) -> &ObjectPath<'_>
[src]
Get a reference to the object path.
pub fn interface(&self) -> &str
[src]
Get a reference to the interface.
pub async fn introspect(&self) -> Result<String>
[src]
Introspect the associated object, and return the XML description.
See the xml module for parsing the result.
pub async fn get_property<T>(&self, property_name: &str) -> Result<T> where
T: TryFrom<OwnedValue>,
[src]
T: TryFrom<OwnedValue>,
Get the property property_name
.
Effectively, call the Get
method of the org.freedesktop.DBus.Properties
interface.
pub async fn set_property<'t, T: 't>(
&self,
property_name: &str,
value: T
) -> Result<()> where
T: Into<Value<'t>>,
[src]
&self,
property_name: &str,
value: T
) -> Result<()> where
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<B>(
&self,
method_name: &str,
body: &B
) -> Result<Message> where
B: Serialize + Type,
[src]
&self,
method_name: &str,
body: &B
) -> Result<Message> where
B: Serialize + Type,
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<B, R>(&self, method_name: &str, body: &B) -> Result<R> where
B: Serialize + Type,
R: DeserializeOwned + Type,
[src]
B: Serialize + Type,
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 receive_signal(
&self,
signal_name: &'static str
) -> Result<SignalStream<'a>>
[src]
&self,
signal_name: &'static str
) -> Result<SignalStream<'a>>
Create a stream for signal named signal_name
.
If the associated connnection is to a bus, a match rule is added for the signal on the bus
so that the bus sends us the signals. Since this match rule needs to be removed when you're
done with the stream, a synchronous D-Bus method call is made in the destructor of the
stream. If you'd like to avoid this, you must close the stream explicitly, using the
SignalStream::close
method.
pub async fn connect_signal<H>(
&self,
signal_name: &'static str,
handler: H
) -> Result<()> where
H: FnMut(&'msg Message) -> BoxFuture<'msg, Result<()>> + Send + 'static,
[src]
&self,
signal_name: &'static str,
handler: H
) -> Result<()> where
H: FnMut(&'msg Message) -> BoxFuture<'msg, Result<()>> + Send + 'static,
Register a handler for signal named signal_name
.
Once a handler is successfully registered, call Self::next_signal
to wait for the next
signal to arrive and be handled by its registered handler.
If the associated connnection is to a bus, a match rule is added for the signal on the bus so that the bus sends us the signals.
Errors
This method can fail if addition of the relevant match rule on the bus fails. You can
safely unwrap
the Result
if you're certain that associated connnection is not a bus
connection.
pub async fn disconnect_signal(&self, signal_name: &'static str) -> Result<bool>
[src]
Deregister the handler for the signal named signal_name
.
If the associated connnection is to a bus, the match rule is removed for the signal on the
bus so that the bus stops sending us the signal. This method returns Ok(true)
if a
handler was registered for signal_name
and was removed by this call; Ok(false)
otherwise.
Errors
This method can fail if removal of the relevant match rule on the bus fails. You can
safely unwrap
the Result
if you're certain that associated connnection is not a bus
connection.
pub async fn next_signal(&self) -> Result<Option<Message>>
[src]
Receive and handle the next incoming signal on the associated connection.
This method will wait for signal messages on the associated connection and call any
handlers registered through the Self::connect_signal
method.
If the signal message was handled by a handler, Ok(None)
is returned. Otherwise, the
received message is returned.
pub async fn handle_signal(&self, msg: &Message) -> Result<bool>
[src]
Handle the provided signal message.
Call any handlers registered through the Self::connect_signal
method for the provided
signal message.
If no errors are encountered, Ok(true)
is returned if a handler was found and called for,
the signal; Ok(false)
otherwise.
