Struct logind_zbus::ManagerProxy [−][src]
pub struct ManagerProxy<'a>(_);
Expand description
Proxy wrapper for the logind Manager
dbus interface
Example
use logind_zbus::ManagerProxy;
use zbus::blocking::Connection;
let connection = Connection::system().unwrap();
let manager = ManagerProxy::new(&connection).unwrap();
assert!(manager.can_suspend().is_ok());
Notes
All connect_*
functions are signals and each of these functions
names reflect the underlying generated Proxy call. If desired the wrapped function
can be bypassed with:
*<ManagerProxy>.connect_<function name>()
Implementations
Brings the session with the specified ID into the foreground
Brings the session with the specified ID into the foreground if the seat ID matches
Used to assign a specific device to a specific seat. The device is identified by its /sys/ path and must be eligible for seat assignments

Methods from Deref<Target = Proxy<'a>>
Get a reference to the associated connection.
Get a reference to the destination service name.
Get a reference to the object path.
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>,
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.
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 fn get_property<T>(&self, property_name: &str) -> Result<T, Error> where
T: TryFrom<OwnedValue>,
<T as TryFrom<OwnedValue>>::Error: Into<Error>,
pub 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 or call the Get
method of the
org.freedesktop.DBus.Properties
interface.
Set the property property_name
.
Effectively, call the Set
method of the org.freedesktop.DBus.Properties
interface.
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).
Call a method and return the reply body.
Use call_method
instead if you need to deserialize the reply manually/separately.
Call a method without expecting a reply
This sets the NoReplyExpected
flag on the calling message and does not wait for a reply.
pub fn receive_signal<'m, M>(
&self,
signal_name: M
) -> Result<SignalIterator<'a>, Error> where
'm: 'a,
M: TryInto<MemberName<'m>>,
<M as TryInto<MemberName<'m>>>::Error: Into<Error>,
pub fn receive_signal<'m, M>(
&self,
signal_name: M
) -> Result<SignalIterator<'a>, Error> where
'm: 'a,
M: TryInto<MemberName<'m>>,
<M as TryInto<MemberName<'m>>>::Error: Into<Error>,
Create a stream for signal named signal_name
.
Errors
Apart from general I/O errors that can result from socket communications, calling this method will also result in an error if the destination service has not yet registered its well-known name with the bus (assuming you’re using the well-known name as destination).
Create a stream for all signals emitted by this service.

pub fn receive_property_changed<'name, T>(

pub fn receive_property_changed<'name, T>(
&self,
name: &'name str
) -> PropertyIterator<'a, T> where
'name: 'a,
Get an iterator to receive 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.
