Struct BatchBuilder 

pub struct BatchBuilder<'c, AUTH> { /* private fields */ }

Accumulates transactions from one or more local accounts and submits them as one proven batch via the node’s SubmitProvenBatch endpoint. See the module-level docs for the full usage and error semantics.

Implementations

impl<AUTH> BatchBuilder<'_, AUTH>

pub fn len(&self) -> usize

Number of successfully-pushed transactions in this batch.

pub fn is_empty(&self) -> bool

True if no transaction has been pushed yet.

impl<AUTH> BatchBuilder<'_, AUTH>

where AUTH: TransactionAuthenticator + Sync + 'static,

pub async fn submit(self) -> Result<BlockNumber, ClientError>

Assemble the ProposedBatch, prove it, submit it via the client’s RPC, and atomically apply the per-transaction updates to the local store.

Returns the node’s chain tip at submission (not the block the batch is committed). The submitted transactions are recorded locally as pending; call sync_state to get the block they commit in.

pub async fn push( self, account_id: AccountId, req: TransactionRequest, ) -> Result<BatchBuilder<'_, AUTH>, ClientError>

Execute req against the batch’s in-memory state for account_id, prove it using the client’s configured prover, and append the resulting proven transaction to the batch. The first push for a given account lazily loads its state from the store.

Consumes the builder and returns it on success. On failure the builder is dropped along with every transaction accumulated so far; the caller cannot recover the partial batch.
