reth_transaction_pool::pool

Struct ParkedPool

Source 
pub struct ParkedPool<T: ParkedOrd> { /* private fields */ }
Expand description

A pool of transactions that are currently parked and are waiting for external changes (e.g. basefee, ancestor transactions, balance) that eventually move the transaction into the pending pool.

This pool is a bijection: at all times each set (best, by_id) contains the same transactions.

Note: This type is generic over ParkedPool which enforces that the underlying transaction type is ValidPoolTransaction wrapped in an Arc.

Implementations§

Source§

impl<T: ParkedOrd> ParkedPool<T>

Source

pub fn add_transaction(&mut self, tx: Arc<ValidPoolTransaction<T::Transaction>>)

Adds a new transactions to the pending queue.

§Panics

If the transaction is already included.

Source

pub fn truncate_pool( &mut self, limit: SubPoolLimit, ) -> Vec<Arc<ValidPoolTransaction<T::Transaction>>>

Truncates the pool by removing transactions, until the given SubPoolLimit has been met.

This is done by first ordering senders by the last time they have submitted a transaction

Uses sender ids sorted by each sender’s last submission id. Senders with older last submission ids are first. Note that last submission ids are the newest submission id for that sender, so this sorts senders by the last time they submitted a transaction in descending order. Senders that have least recently submitted a transaction are first.

Then, for each sender, all transactions for that sender are removed, until the pool limits have been met.

Any removed transactions are returned.
