EvictionKey

tempo_transaction_pool::tt_2d_pool

Struct EvictionKey 

Source 
struct EvictionKey {
    tx: Arc<AA2dInternalTransaction>,
    tx_id: AA2dTransactionId,
}
Expand description

Key for ordering transactions by eviction priority.

Orders by:

  1. Priority ascending (lowest priority evicted first)
  2. Submission ID descending (newer transactions evicted first among same priority)

This is the inverse of the execution order (where highest priority, oldest submission wins). Newer transactions are evicted first to preserve older transactions that have been waiting longer.

Fields§

§tx: Arc<AA2dInternalTransaction>

The wrapped transaction containing all needed data.

§tx_id: AA2dTransactionId

The transaction’s unique identifier (cached for lookup during eviction). We cache this because deriving it from the transaction requires aa_transaction_id() which returns an Option and does more work.
