Transaction pool interface

Required methods

fn transactions(&self) -> Vec<(H, <B as Block>::Extrinsic), Global>

Get transactions from the pool that are ready to be propagated.

fn hash_of(&self, transaction: &<B as Block>::Extrinsic) -> H

Get hash of transaction.

fn import(
    &self,
    transaction: <B as Block>::Extrinsic
) -> Pin<Box<dyn Future<Output = TransactionImport> + Send + 'static, Global>>

Import a transaction into the pool.

This will return future.

fn on_broadcasted(
    &self,
    propagations: HashMap<H, Vec<String, Global>, RandomState>
)

Notify the pool about transactions broadcast.

fn transaction(&self, hash: &H) -> Option<<B as Block>::Extrinsic>

Get transaction by hash.
