Trait PruneCheckpointReader 

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

    // Provided method
    fn get_prune_checkpoints_for_availability(
        &self,
    ) -> Result<Vec<(PruneSegment, PruneCheckpoint)>, ProviderError> { ... }
}

Available on crate feature provider only.

The trait for fetching prune checkpoint related data.

Required Methods

fn get_prune_checkpoint( &self, segment: PruneSegment, ) -> Result<Option<PruneCheckpoint>, ProviderError>

Fetch the prune checkpoint for the given segment.

fn get_prune_checkpoints( &self, ) -> Result<Vec<(PruneSegment, PruneCheckpoint)>, ProviderError>

Fetch all the prune checkpoints.

Provided Methods

fn get_prune_checkpoints_for_availability( &self, ) -> Result<Vec<(PruneSegment, PruneCheckpoint)>, ProviderError>

Fetch checkpoints for reporting data availability, accounting for data still retained in other storage backends. This does not modify the stored checkpoints.

The default returns the stored checkpoints. Implementations may lower their block and transaction numbers when continuous coverage can be verified, preserving the prune mode. Use Self::get_prune_checkpoints for pruning progress instead.

Dyn Compatibility

This trait is dyn compatible.

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