Trait PruneCheckpointReader 

pub trait PruneCheckpointReader: Send + Sync {
    // Required methods
    fn get_prune_checkpoint(
        &self,
        segment: PruneSegment,
    ) -> Result<Option<PruneCheckpoint>, ProviderError>;
    fn get_prune_checkpoints(
        &self,
    ) -> Result<Vec<(PruneSegment, PruneCheckpoint)>, ProviderError>;
}

The trait for fetching prune checkpoint related data.
