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( &mut self, account_id: AccountId, req: TransactionRequest, ) -> Result<&mut 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.

The batch is only advanced once the transaction has both executed and been proven, so on failure the builder still holds exactly the transactions it held before the call and remains usable. Returns &mut Self so pushes can be chained.
