Enum PropertyChange

pub enum PropertyChange {
    Volume(Volume),
    Mute(Mute),

    PlaybackState(PlaybackState),
    Position(Position),

    GroupVolumeChangeable(GroupVolumeChangeable),
}

A single property change

#[non_exhaustive] because this enum is public API (re-exported from sonos-sdk) and gains a variant every time a property is added. Without it, every consumer match would be exhaustive-by-default and adding a property would be a breaking change; consumers must include a _ => arm.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Implementations

impl PropertyChange

pub fn apply( &self, store: &mut StateStore, speaker_id: &SpeakerId, stamp: WriteStamp, ) -> WriteOutcome

Apply this change to the store using scope-based routing

Speaker-scoped properties are stored in speaker_props, group-scoped properties resolve speaker→group and store in group_props.

Returns the WriteOutcome — Changed only if the value actually changed and stamp was not older than the stored observation.

pub fn key(&self) -> &'static str

Get the property key for this change

pub fn scope(&self) -> Scope

Get the scope of this property

pub fn service(&self) -> Service

Get the service this property belongs to

Trait Implementations

impl Clone for PropertyChange

fn clone(&self) -> PropertyChange

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PropertyChange

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.
