Struct OtaState 

pub struct OtaState { /* private fields */ }

The OTA Requestor’s reported update state: the UpdateState, UpdateStateProgress and UpdatePossible attributes.

Held separately from Providers because it is transient runtime state, not configuration. The application reports progress through an OtaUpdate session obtained from initiate_update.

Because progress is reported from the application’s own update loop (outside any cluster-handler ctx), the reporting calls take the data model’s AttrChangeNotifier (typically the InteractionModel) so each change bumps the cluster’s data version and wakes subscribers. It is passed in rather than stored because the InteractionModel is constructed after this state (it borrows it), so there is never a moment at which it could be stored here.

Implementations

impl OtaState

pub const fn new(endpoint_id: u16) -> OtaState

Create idle, update-possible state for the endpoint hosting the OTA Requestor cluster (the one whose OtaRequestorHandler reads this state), so change notifications target the right cluster instance.

pub fn set_update_possible( &self, notifier: &dyn AttrChangeNotifier, possible: bool, )

Set the UpdatePossible attribute (e.g. false when the battery is too low to apply an update), notifying notifier of the change.

pub fn initiate_update<'a>( &'a self, notifier: &'a dyn AttrChangeNotifier, ) -> OtaUpdate<'a>

Begin an update session, reporting changes through notifier. The returned OtaUpdate reports progress; on complete - or if dropped without it - the reported state returns to Idle (UpdateStateEnum has no dedicated failure value).
