    the code of the file until where you have to start completion: //! Reth's transaction pool implementation.
//!
//! This crate provides a generic transaction pool implementation.
//!
//! ## Functionality
//!
//! The transaction pool is responsible for
//!
//!    - recording incoming transactions
//!    - providing existing transactions
//!    - ordering and providing the best transactions for block production
//!    - monitoring memory footprint and enforce pool size limits
//!    - storing blob data for transactions in a separate blobstore on insertion
//!
//! ## Assumptions
//!
//! ### Transaction type
//!
//! The pool e
    
//! async fn t<C>(client: C)  where C: StateProviderFactory + BlockReaderIdExt + ChainSpecProvider + Clone + 'static{
//!     let blob_store = InMemoryBlobStore::default();
//!     let pool = Pool::eth_pool(
//!         TransactionValidationTaskExecutor::eth(client, MAINNET.clone(), blob_store.clone(), TokioTaskExecutor::default()),
//!         blob_store,
//!         Default::default(),
//!     );
//!   let mut transactions = pool.pending_transactions_listener();
//!   tokio::task::spawn( async move {
//!      while let Some(tx) = transactions.recv().await {
//!          println!("New transaction: {:?}", tx);
//!      }
//!   });
//!
//!   // do something useful with the pool, like RPC integration
//!
//! # }
