Struct zbus::InterfaceRef [−][src]
pub struct InterfaceRef<I> { /* fields omitted */ }
Expand description
Wrapper over an interface, along with its corresponding SignalContext
instance. A reference to the underlying interface may be obtained via
InterfaceRef::get
and InterfaceRef::get_mut
.
Implementations
Get a reference to the underlying interface.
Get a reference to the underlying interface.
WARNINGS: Since the ObjectServer
will not be able to access the interface in question
until the return value of this method is dropped, it is highly recommended that the scope
of the interface returned is restricted.
Errors
If the interface at this instance’s path is not valid, Error::InterfaceNotFound
error is
returned.
Examples
struct MyIface(u32);
#[dbus_interface(name = "org.myiface.MyIface")]
impl MyIface {
#[dbus_interface(property)]
async fn count(&self) -> u32 {
self.0
}
}
// Setup connection and object_server etc here and then in another part of the code:
let mut object_server = connection.object_server();
let iface_ref = object_server.interface::<_, MyIface>(path).await?;
let mut iface = iface_ref.get_mut().await;
iface.0 = 42;
iface.count_changed(iface_ref.signal_context()).await?;
