Expand description

One step in an operator chain (same subtask, in-process).

Required Methods§

Source

fn open<'life0, 'life1, 'async_trait>( &'life0 mut self, ctx: &'life1 mut RuntimeContext, ) -> Pin<Box<dyn Future<Output = StreamResult<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Source

fn close<'life0, 'life1, 'async_trait>( &'life0 mut self, ctx: &'life1 mut RuntimeContext, ) -> Pin<Box<dyn Future<Output = StreamResult<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Source

fn on_checkpoint<'life0, 'life1, 'life2, 'async_trait>( &'life0 mut self, runtime: &'life1 mut RuntimeContext, ckpt: &'life2 CheckpointContext, ) -> Pin<Box<dyn Future<Output = StreamResult<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Source

fn on_checkpoint_end<'life0, 'life1, 'life2, 'async_trait>( &'life0 mut self, runtime: &'life1 mut RuntimeContext, ckpt: &'life2 CheckpointContext, ) -> Pin<Box<dyn Future<Output = StreamResult<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Provided Methods§

Source

fn drain_counters(&mut self) -> (u64, u64)

Returns (input_delta, output_delta) and resets the internal last-pointers

Source

fn collect_metrics(&self) -> HashMap<String, f64>

Delegates to the underlying operator for custom metrics

Dyn Compatibility§

This trait is dyn compatible.

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