Available on crate feature provider only.

The trait for fetching stage checkpoint related data.

Required Methods

fn get_stage_checkpoint( &self, id: StageId, ) -> Result<Option<StageCheckpoint>, ProviderError>

Fetch the checkpoint for the given stage.

fn get_stage_checkpoint_progress( &self, id: StageId, ) -> Result<Option<Vec<u8>>, ProviderError>

Get stage checkpoint progress.

fn get_all_checkpoints( &self, ) -> Result<Vec<(String, StageCheckpoint)>, ProviderError>

Reads all stage checkpoints and returns a list with the name of the stage and the checkpoint data.
