Block builder provider

Required Methods

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

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