Struct ScenesState 

pub struct ScenesState<const N: usize, const M: usize = rs_matter::::dm::clusters::scenes::ScenesState::{constant#0}> { /* private fields */ }

Caller-owned per-device Scenes state — the scene table plus per-fabric CurrentScene bookkeeping. Shared across all endpoints exposing the cluster.

Const generics:

• N — total scene-table capacity (rows across all fabrics + endpoints).
• M — per-scene EFS blob capacity in bytes. Bump it when wiring ColorControl into a multi-feature deployment whose captured EFS exceeds MAX_EXT_FIELDS_LEN. Total static RAM is roughly N * (M + overhead).

Implementations

impl<const N: usize, const M: usize> ScenesState<N, M>

pub const fn new() -> ScenesState<N, M>

pub fn init() -> impl Init<ScenesState<N, M>>

In-place initializer.

impl<const N: usize, const M: usize> ScenesState<N, M>

pub fn load_persist<S>(&self, store: S, buf: &mut [u8]) -> Result<(), Error>

where S: KvBlobStore,

Re-hydrate the scene table and per-fabric CurrentScene bookkeeping from store under SCENES_KEY. A missing key (first boot or cleared persistence) leaves the registry empty.

Called on startup via the LifecycleOp::Startup lifecycle operation delivered to the ScenesHandler borrowing this state.

pub fn reset_persist<S>(&self, store: S, buf: &mut [u8]) -> Result<(), Error>

where S: KvBlobStore,

Reset the scene table and per-fabric CurrentScene bookkeeping to empty and remove the persisted blob from store (under SCENES_KEY).

Called on factory reset via the LifecycleOp::FactoryReset lifecycle operation delivered to the ScenesHandler borrowing this state.

pub fn remove_for_fabric(&self, fab_idx: NonZero<u8>) -> bool

Drop every scene-table row and CurrentScene slot belonging to fab_idx, returning whether anything was removed.

Called on fabric removal via the LifecycleOp::FabricRemoval lifecycle operation delivered to the ScenesHandler instance(s) borrowing this state. Idempotent, since each borrowing handler instance receives the (broadcast) lifecycle operation.

Trait Implementations

impl<const N: usize, const M: usize> Default for ScenesState<N, M>

fn default() -> ScenesState<N, M>

Returns the “default value” for a type.

impl<const N: usize, const M: usize> SceneInvalidator for ScenesState<N, M>

fn scenable_attribute_changed(&self, endpoint_id: u16)

Flip SceneValid → false for every recalled scene on endpoint_id, across all fabrics. No-op when no fabric has a scene recalled there.
