Struct PropertyChanged

pub struct PropertyChanged<'a, T> { /* private fields */ }

Expand description

A property changed event.

The property changed event generated by PropertyStream.

Implementations§

impl<T> PropertyChanged<'_, T>

pub fn name(&self) -> &str

The name of the property that changed.

pub async fn get_raw(&self) -> Result<impl Deref<Target = Value<'static>> + '_>

Get the raw value of the property that changed.

If the notification signal contained the new value, it has been cached already and this call will return that value. Otherwise (i.e. invalidated property), a D-Bus call is made to fetch and cache the new value.

impl<T> PropertyChanged<'_, T>
where T: TryFrom<OwnedValue>, T::Error: Into<Error>,

pub async fn get(&self) -> Result<T>

Get the value of the property that changed.

If the notification signal contained the new value, it has been cached already and this call will return that value. Otherwise (i.e. invalidated property), a D-Bus call is made to fetch and cache the new value.
