Struct GroupPropertyHandle 

pub struct GroupPropertyHandle<P: SonosProperty> { /* private fields */ }

Generic property handle for group-scoped properties

Provides the same get/fetch/watch/unwatch pattern as PropertyHandle, but reads from the group property store and executes API calls against the group’s coordinator.

Implementations

impl<P: SonosProperty> GroupPropertyHandle<P>

pub fn new(context: Arc<GroupContext>) -> Self

Create a new GroupPropertyHandle from a shared GroupContext

pub fn get(&self) -> Option<P>

Get cached group property value (sync, instant, no network call)

pub fn watch(&self) -> Result<WatchStatus<P>, SdkError>

Registers using the coordinator’s speaker ID so the event worker correctly routes events through to system.iter().

pub fn unwatch(&self)

Stop watching this group property (sync)

pub fn is_watched(&self) -> bool

Check if this group property is currently being watched

pub fn group_id(&self) -> &GroupId

Get the group ID this handle is associated with

impl<P: GroupFetchable> GroupPropertyHandle<P>

pub fn fetch(&self) -> Result<P, SdkError>

Fetch fresh value from coordinator + update group cache (sync)

Trait Implementations

impl<P: Clone + SonosProperty> Clone for GroupPropertyHandle<P>

fn clone(&self) -> GroupPropertyHandle<P>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)
