Required methods

pub fn submit_at(
    &self,
    at: &BlockId<Self::Block>,
    source: TransactionSource,
    xts: Vec<<Self::Block as Block>::Extrinsic, Global>
) -> Pin<Box<dyn Future<Output = Result<Vec<Result<Self::Hash, Self::Error>, Global>, Self::Error>> + 'static + Send, Global>>[src]

Returns a future that imports a bunch of unverified transactions to the pool.

pub fn submit_one(
    &self,
    at: &BlockId<Self::Block>,
    source: TransactionSource,
    xt: <Self::Block as Block>::Extrinsic
) -> Pin<Box<dyn Future<Output = Result<Self::Hash, Self::Error>> + 'static + Send, Global>>[src]

Returns a future that imports one unverified transaction to the pool.

pub fn submit_and_watch(
    &self,
    at: &BlockId<Self::Block>,
    source: TransactionSource,
    xt: <Self::Block as Block>::Extrinsic
) -> Pin<Box<dyn Future<Output = Result<Box<dyn Stream<Item = TransactionStatus<Self::Hash, <Self::Block as Block>::Hash>> + 'static + Send + Unpin, Global>, Self::Error>> + 'static + Send, Global>>[src]

Returns a future that import a single transaction and starts to watch their progress in the pool.

pub fn ready_at(
    &self,
    at: <<Self::Block as Block>::Header as Header>::Number
) -> Pin<Box<dyn Future<Output = Box<dyn Iterator<Item = Arc<Self::InPoolTransaction>> + 'static + Send, Global>> + 'static + Send, Global>>[src]

Get an iterator for ready transactions ordered by priority.

Guarantees to return only when transaction pool got updated at at block. Guarantees to return immediately when None is passed.

pub fn ready(
    &self
) -> Box<dyn Iterator<Item = Arc<Self::InPoolTransaction>> + 'static + Send, Global>[src]

Get an iterator for ready transactions ordered by priority.

pub fn remove_invalid(
    &self,
    hashes: &[Self::Hash]
) -> Vec<Arc<Self::InPoolTransaction>, Global>[src]

Remove transactions identified by given hashes (and dependent transactions) from the pool.

pub fn status(&self) -> PoolStatus[src]

Returns pool status.

pub fn import_notification_stream(&self) -> Receiver<Self::Hash>[src]

Return an event stream of transactions imported to the pool.

pub fn on_broadcasted(
    &self,
    propagations: HashMap<Self::Hash, Vec<String, Global>, RandomState>
)[src]

Notify the pool about transactions broadcast.

pub fn hash_of(&self, xt: &<Self::Block as Block>::Extrinsic) -> Self::Hash[src]

Returns transaction hash

pub fn ready_transaction(
    &self,
    hash: &Self::Hash
) -> Option<Arc<Self::InPoolTransaction>>[src]

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