    // Required methods
    fn get_stage_checkpoint(
        &self,
        id: StageId,
    ) -> ProviderResult<Option<StageCheckpoint>>;

}

The trait for fetching stage checkpoint related data.

Required Methods

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

Fetch the checkpoint for the given stage.

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

Get stage checkpoint progress.

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

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