function assertIsParallelTransactionPlanResult<
    TContext,
    TTransactionMessage,
    TSingle,
>(
    plan,
): asserts plan is Readonly<{
    kind: 'parallel';
    plans: TransactionPlanResult<
        TContext,

}>;

Asserts that the given transaction plan result is a ParallelTransactionPlanResult.

Type Parameters

Type Parameter	Default type
`TContext` extends `TransactionPlanResultContext`	`TransactionPlanResultContext`
`TTransactionMessage` extends `TransactionMessage` & `TransactionMessageWithFeePayer`<`string`>	`TransactionMessage` & `TransactionMessageWithFeePayer`<`string`>
`TSingle` extends `SingleTransactionPlanResult`<`TContext`, `TTransactionMessage`>	`SingleTransactionPlanResult`<`TContext`, `TTransactionMessage`>

Parameters

Parameter	Type	Description
`plan`	`TransactionPlanResult`<`TContext`, `TTransactionMessage`, `TSingle`>	The transaction plan result to assert.

Returns

asserts plan is Readonly<{ kind: "parallel"; plans: TransactionPlanResult<TContext, TTransactionMessage, TSingle>[]; planType: "transactionPlanResult" }>

Throws

Throws a SolanaError with code SOLANA_ERROR__INSTRUCTION_PLANS__UNEXPECTED_TRANSACTION_PLAN_RESULT if the result is not a parallel transaction plan result.

Example

const result: TransactionPlanResult = parallelTransactionPlanResult([resultA, resultB]);
 
assertIsParallelTransactionPlanResult(result);
console.log(result.plans.length); // TypeScript knows this is a ParallelTransactionPlanResult.
