Transaction pool interface

Required Methods

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

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

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

Get hash of transaction.

fn import(&self, transaction: B::Extrinsic) -> TransactionImportFuture

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::Extrinsic>>

Get transaction by hash.
