Chain info for derive_super_segments_for_block().

Must have access to enough parent blocks.

Required Methods

fn get_genesis_segment_root( &self, ) -> Result<SegmentRoot, DeriveSuperSegmentForBlockError>

Get genesis segment root of the beacon chain

fn segment_roots_for_block( &self, block_number: BlockNumber, ) -> impl ExactSizeIterator<Item = ShardSegmentRoot> + Send + Sync + 'static

Get segment roots that are expected to be included at specified block number

fn previous_super_segment_header( &self, block_number: BlockNumber, ) -> Option<SuperSegmentHeader>

Returns the previous super segment header for the block built with the specified number

fn shard_segment_roots( &self, block_number: BlockNumber, ) -> Result<StdArc<[ShardSegmentRoot]>, ShardSegmentRootsError>

Returns intermediate and leaf shard segment roots included in the specified block number.

NOTE: Since blocks at this depth are already confirmed, only a block number is needed as a reference.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
