Expand description

An event emitted by a Pipeline.

It is possible for multiple of these events to be emitted over the duration of a pipeline’s execution since:

  • Other stages may ask the pipeline to unwind
  • The pipeline will loop indefinitely unless a target block is set

Variants§

§

Prepare

Emitted when a stage is about to be prepared for a run.

Fields

§pipeline_stages_progress: PipelineStagesProgress

Pipeline stages progress.

§stage_id: StageId

The stage that is about to be run.

§checkpoint: Option<StageCheckpoint>

The previous checkpoint of the stage.

§target: Option<BlockNumber>

The block number up to which the stage is running, if known.

§

Run

Emitted when a stage is about to be run.

Fields

§pipeline_stages_progress: PipelineStagesProgress

Pipeline stages progress.

§stage_id: StageId

Fields

§pipeline_stages_progress: PipelineStagesProgress

§

Error

Emitted when a stage encounters an error either during execution or unwinding.

Fields

§stage_id: StageId

§

Skipped

Emitted when a stage was skipped due to it’s run conditions not being met:

  • The stage might have progressed beyond the point of our target block
  • The stage might not need to be unwound since it has not progressed past the unwind target
  • The stage requires that the pipeline has reached the tip, but it has not done so yet

Fields

§stage_id: StageId

The stage that was skipped.
