Block Writer

Required Associated Types

type Body: Send + Sync

The body this writer can write.

Required Methods

fn insert_block( &self, block: SealedBlockWithSenders, ) -> ProviderResult<StoredBlockBodyIndices>

Insert full block and make it canonical. Parent tx num and transition id is taken from parent block in database.

Return [StoredBlockBodyIndices] that contains indices of the first and last transactions and transition in the block.

fn append_block_bodies( &self, bodies: impl Iterator<Item = (BlockNumber, Option<Self::Body>)>, ) -> ProviderResult<()>

Appends a batch of block bodies extending the canonical chain. This is invoked during Bodies stage and does not write to TransactionHashNumbers and TransactionSenders tables which are populated on later stages.

Bodies are passed as Options, if body is None the corresponding block is empty.

fn append_blocks_with_state( &self, blocks: Vec<SealedBlockWithSenders>, execution_outcome: ExecutionOutcome, hashed_state: HashedPostStateSorted, trie_updates: TrieUpdates, ) -> ProviderResult<()>

Appends a batch of sealed blocks to the blockchain, including sender information, and updates the post-state.

Inserts the blocks into the database and updates the state with provided BundleState.

Parameters

• blocks: Vector of SealedBlockWithSenders instances to append.
• state: Post-state information to update after appending.

Returns

Returns Ok(()) on success, or an error if any operation fails.

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.
