Implementations

impl<PoolApi, Block> BasicPool<PoolApi, Block>where Block: BlockT, PoolApi: ChainApi<Block = Block> + 'static,

pub fn new_test( pool_api: Arc<PoolApi>, best_block_hash: Block::Hash, finalized_hash: Block::Hash ) -> (Self, Pin<Box<dyn Future<Output = ()> + Send>>)

Create new basic transaction pool with provided api and custom revalidation type.

pub fn pool(&self) -> &Arc<Pool<PoolApi>>

Gets shared reference to the underlying pool.

pub fn api(&self) -> &PoolApi

type Block = Block

Block type.

type Hash = <<FullChainApi<Client, Block> as ChainApi>::Block as Block>::Hash

fn submit_local( &self, at: Block::Hash, xt: LocalTransactionFor<Self> ) -> Result<Self::Hash, Self::Error>

Submits the given local unverified transaction to the pool blocking the current thread for any necessary pre-verification. NOTE: It MUST NOT be used for transactions that originate from the network or RPC, since the validation is performed with TransactionSource::Local.
