Transaction pool interface

Required Methods

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

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>>

Import a transaction into the pool.

This will return future.

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

Notify the pool about transactions broadcast.

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

Get transaction by hash.
