Struct BlockBuilder 

pub struct BlockBuilder { /* private fields */ }

Builds a Block for tests with a header that stays consistent with its body (the header is computed via Block::new), so it round-trips through serialization and storage. Tests start from an empty body and add messages, events, and so on.

Implementations

impl BlockBuilder

pub fn new(chain_id: ChainId, height: BlockHeight) -> Self

Starts building a block at the given chain and height with an empty body.

pub fn with_state_hash(self, state_hash: CryptoHash) -> Self

Sets the execution state hash recorded in the header.

pub fn with_transaction(self, transaction: Transaction) -> Self

Appends a transaction to the block’s inputs.

pub fn with_messages(self, messages: Vec<OutgoingMessage>) -> Self

Appends one transaction’s outgoing messages to the body.

pub fn with_events(self, events: Vec<Event>) -> Self

Appends one transaction’s events to the body.

pub fn with_oracle_responses( self, oracle_responses: Vec<OracleResponse>, ) -> Self

Appends one transaction’s oracle responses to the body.

pub fn with_blobs(self, blobs: Vec<Blob>) -> Self

Appends one transaction’s created blobs to the body.

pub fn with_operation_result(self, operation_result: OperationResult) -> Self

Appends an operation result to the body.

pub fn build(self) -> Block

Builds the block, computing a header that is consistent with the body.
