where 'life0: 'async_trait, ForkAwareTxPool<ChainApi, Block>: 'async_trait,

Submits multiple transactions and returns a future resolving to the submission results.

Actual transactions submission process is delegated to the ViewStore internal instance.

The internal limits of the pool are checked. The results of submissions to individual views are reduced to single result. Refer to reduce_multiview_result for more details.

fn submit_one<'life0, 'async_trait>( &'life0 self, _at: <<ForkAwareTxPool<ChainApi, Block> as TransactionPool>::Block as Block>::Hash, source: TransactionSource, xt: <<ForkAwareTxPool<ChainApi, Block> as TransactionPool>::Block as Block>::Extrinsic, ) -> Pin<Box<dyn Future<Output = Result<<ForkAwareTxPool<ChainApi, Block> as TransactionPool>::Hash, <ForkAwareTxPool<ChainApi, Block> as TransactionPool>::Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, ForkAwareTxPool<ChainApi, Block>: 'async_trait,

Submits a single transaction and returns a future resolving to the submission results.

Actual transaction submission process is delegated to the submit_at function.

fn submit_and_watch<'life0, 'async_trait>( &'life0 self, at: <<ForkAwareTxPool<ChainApi, Block> as TransactionPool>::Block as Block>::Hash, source: TransactionSource, xt: <<ForkAwareTxPool<ChainApi, Block> as TransactionPool>::Block as Block>::Extrinsic, ) -> Pin<Box<dyn Future<Output = Result<Pin<Box<dyn Stream<Item = TransactionStatus<<ForkAwareTxPool<ChainApi, Block> as TransactionPool>::Hash, <<ForkAwareTxPool<ChainApi, Block> as TransactionPool>::Block as Block>::Hash>> + Send>>, <ForkAwareTxPool<ChainApi, Block> as TransactionPool>::Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, ForkAwareTxPool<ChainApi, Block>: 'async_trait,

Submits a transaction and starts to watch its progress in the pool, returning a stream of status updates.

Actual transaction submission process is delegated to the ViewStore internal instance.

fn remove_invalid( &self, hashes: &[<ForkAwareTxPool<ChainApi, Block> as TransactionPool>::Hash], ) -> Vec<Arc<<ForkAwareTxPool<ChainApi, Block> as TransactionPool>::InPoolTransaction>>

Intended to remove transactions identified by the given hashes, and any dependent transactions, from the pool. In current implementation this function only outputs the error. Seems that API change is needed here to make this call reasonable.

fn status(&self) -> PoolStatus

Returns the pool status which includes information like the number of ready and future transactions.

Currently the status for the most recently notified best block is returned (for which maintain process was accomplished).

fn import_notification_stream( &self, ) -> Receiver<<<ChainApi as ChainApi>::Block as Block>::Hash>

Return an event stream of notifications when transactions are imported to the pool.

Consumers of this stream should use the ready method to actually get the pending transactions in the right order.

fn hash_of( &self, xt: &<<ForkAwareTxPool<ChainApi, Block> as TransactionPool>::Block as Block>::Extrinsic, ) -> <ForkAwareTxPool<ChainApi, Block> as TransactionPool>::Hash

Returns the hash of a given transaction.

fn on_broadcasted( &self, propagations: HashMap<<ForkAwareTxPool<ChainApi, Block> as TransactionPool>::Hash, Vec<String>>, )

Notifies the pool about the broadcasting status of transactions.

fn ready_transaction( &self, tx_hash: &<ForkAwareTxPool<ChainApi, Block> as TransactionPool>::Hash, ) -> Option<Arc<<ForkAwareTxPool<ChainApi, Block> as TransactionPool>::InPoolTransaction>>

Return specific ready transaction by hash, if there is one.

Currently the ready transaction is returned if it exists for the most recently notified best block (for which maintain process was accomplished).

fn ready_at<'life0, 'async_trait>( &'life0 self, at: <<ForkAwareTxPool<ChainApi, Block> as TransactionPool>::Block as Block>::Hash, ) -> Pin<Box<dyn Future<Output = Box<dyn ReadyTransactions<Item = Arc<Transaction<<<ChainApi as ChainApi>::Block as Block>::Hash, Arc<<<ChainApi as ChainApi>::Block as Block>::Extrinsic>>>> + Send>> + Send + 'async_trait>>

where 'life0: 'async_trait, ForkAwareTxPool<ChainApi, Block>: 'async_trait,

Returns an iterator for ready transactions at a specific block, ordered by priority.

fn ready( &self, ) -> Box<dyn ReadyTransactions<Item = Arc<Transaction<<<ChainApi as ChainApi>::Block as Block>::Hash, Arc<<<ChainApi as ChainApi>::Block as Block>::Extrinsic>>>> + Send>

Returns an iterator for ready transactions, ordered by priority.

Currently the set of ready transactions is returned if it exists for the most recently notified best block (for which maintain process was accomplished).

fn futures( &self, ) -> Vec<<ForkAwareTxPool<ChainApi, Block> as TransactionPool>::InPoolTransaction>

Returns a list of future transactions in the pool.

Currently the set of future transactions is returned if it exists for the most recently notified best block (for which maintain process was accomplished).

fn ready_at_with_timeout<'life0, 'async_trait>( &'life0 self, at: <<ForkAwareTxPool<ChainApi, Block> as TransactionPool>::Block as Block>::Hash, timeout: Duration, ) -> Pin<Box<dyn Future<Output = Box<dyn ReadyTransactions<Item = Arc<Transaction<<<ChainApi as ChainApi>::Block as Block>::Hash, Arc<<<ChainApi as ChainApi>::Block as Block>::Extrinsic>>>> + Send>> + Send + 'async_trait>>

where 'life0: 'async_trait, ForkAwareTxPool<ChainApi, Block>: 'async_trait,

Returns a set of ready transactions at a given block within the specified timeout.

If the timeout expires before the maintain process is accomplished, a best-effort set of transactions is returned (refer to ready_at_light).
