Implementations

impl PropertiesCache

fn new( proxy: PropertiesProxy<'static>, interface: InterfaceName<'static>, executor: &Executor<'_>, uncached_properties: HashSet<Str<'static>>, ) -> (Arc<Self>, Task<()>)

async fn init( &self, proxy: PropertiesProxy<'static>, interface: InterfaceName<'static>, uncached_properties: HashSet<Str<'static>>, ) -> Result<(PropertiesChangedStream, InterfaceName<'static>, HashSet<Str<'static>>)>

new() runs this in a task it spawns for initialization of properties cache.

async fn keep_updated( &self, prop_changes: PropertiesChangedStream, interface: InterfaceName<'static>, uncached_properties: HashSet<Str<'static>>, ) -> Result<()>

new() runs this in a task it spawns for keeping the cache in sync.

fn update_cache( &self, uncached_properties: &HashSet<Str<'_>>, changed: &HashMap<&str, Value<'_>>, invalidated: &[&str], interface: &InterfaceName<'_>, )

pub(crate) async fn ready(&self) -> Result<()>

Wait for the cache to be populated and return any error encountered during population.
