Block builder provider

Required methods

fn new_block_at<R: Into<RecordProof>>(
    &self,
    parent: &BlockId<Block>,
    inherent_digests: DigestFor<Block>,
    record_proof: R
) -> Result<BlockBuilder<'_, Block, RA, B>>

Create a new block, built on top of parent.

When proof recording is enabled, all accessed trie nodes are saved. These recorded trie nodes can be used by a third party to proof the output of this block builder without having access to the full storage.

fn new_block(
    &self,
    inherent_digests: DigestFor<Block>
) -> Result<BlockBuilder<'_, Block, RA, B>>

Create a new block, built on the head of the chain.
