The handler trait for the cluster.

Required Associated Constants

const CLUSTER: Cluster<'static>

The cluster-metadata corresponding to this handler trait.

Required Methods

fn dataver(&self) -> u32

fn dataver_changed(&self)

async fn handle_reset_watermarks( &self, ctx: impl InvokeContext, ) -> Result<(), Error>

Provided Methods

fn lifecycle( &self, _ctx: impl HandlerContext, _op: LifecycleOp, ) -> Result<(), Error>

fn run( &self, _ctx: impl HandlerContext, ) -> impl Future<Output = Result<(), Error>>

fn thread_metrics<P>( &self, ctx: impl ReadContext, builder: ArrayAttributeRead<ThreadMetricsStructArrayBuilder<P>, ThreadMetricsStructBuilder<P>>, ) -> impl Future<Output = Result<P, Error>>

where P: TLVBuilderParent,

fn current_heap_free( &self, ctx: impl ReadContext, ) -> impl Future<Output = Result<u64, Error>>

fn current_heap_used( &self, ctx: impl ReadContext, ) -> impl Future<Output = Result<u64, Error>>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
