Struct omnisensor::dbus_helpers::SignalProp

pub struct SignalProp<A> {
    data: A,
    msgfn: Arc<dyn Fn(&Path<'_>, &dyn RefArg) -> Option<Message> + Send + Sync>,
    dbuspath: Arc<SensorPath>,
    conn: Arc<SyncConnection>,
}

A dbus property that owns its own data and automatically sends property-change signals on updates.

Fields

data: A

The current value of the property.

msgfn: Arc<dyn Fn(&Path<'_>, &dyn RefArg) -> Option<Message> + Send + Sync>

A function to create a PropetiesChanged signal message when data changes.

dbuspath: Arc<SensorPath>

The dbus path of the object this property belongs to.

conn: Arc<SyncConnection>

The dbus connection via which PropetiesChanged signals are sent.

Implementations

impl<A: PartialEq + RefArg> SignalProp<A>

pub fn new(
    data: A,
    msgfn: &Arc<dyn Fn(&Path<'_>, &dyn RefArg) -> Option<Message> + Send + Sync>,
    dbuspath: &Arc<SensorPath>,
    conn: &Arc<SyncConnection>
) -> Self

Construct a SignalProp with the given members.

pub fn get(&self) -> Awhere
    A: Copy,

Retrieve self’s current value.

pub fn get_clone(&self) -> Awhere
    A: Clone,

Retrieve a clone of self’s current value.

pub fn set(&mut self, newdata: A)

Update self’s value to newdata, emitting a PropertiesChanged signal to dbus if newdata is unequal to self.data’s previous value.

fn send_propchg(&self)

Emit a PropertiesChanged signal to dbus with self’s current value.
