Interface for fetching block data.

Required methods

fn block_body(
    &self,
    id: &BlockId<Block>
) -> Result<Option<Vec<<Block as Block>::Extrinsic>>, Error>

    &self,
    id: &BlockId<Block>
) -> Result<Option<SignedBlock<Block>>, Error>

Get full block by id.

fn block_status(&self, id: &BlockId<Block>) -> Result<BlockStatus, Error>

Get block status.

fn justification(&self, id: &BlockId<Block>) -> Result<Option<Vec<u8>>, Error>
