Struct KeyExpiryTracker 

Source 
struct KeyExpiryTracker {
    expiry_map: BTreeMap<u64, HashSet<KeyId>>,
    key_to_txs: HashMap<KeyId, (u64, HashSet<TxHash>)>,
    tx_to_key: HashMap<TxHash, KeyId>,
}
Expand description

Tracks keychain key expiry timestamps for eviction.

When a keychain-signed transaction enters the pool, we track its (account, key_id) along with the key’s expiry timestamp. When a block’s timestamp passes the expiry, we evict all transactions using that expired key.

Note: We don’t query state here - the expiry is read once when the transaction enters the pool (during validation) and passed to the tracker.

Fields§

§expiry_map: BTreeMap<u64, HashSet<KeyId>>

Maps expiry timestamp -> set of keys that expire at that time.

§key_to_txs: HashMap<KeyId, (u64, HashSet<TxHash>)>

Maps KeyId -> (expiry timestamp, set of transaction hashes using this key).

§tx_to_key: HashMap<TxHash, KeyId>

Reverse map transaction hash -> KeyId for O(1) lookup on removal.

Implementations§

Source§

impl KeyExpiryTracker

Source

fn track( &mut self, account: Address, key_id: Address, expiry: u64, tx_hash: TxHash, )

Track a keychain transaction with its key expiry timestamp.

Call this when a keychain-signed transaction enters the pool. The expiry should be read from the AccountKeychain storage during validation.

Source

fn untrack(&mut self, hash: &TxHash)

Removes a single transaction hash from key expiry tracking.

Source

fn drain_expired(&mut self, tip_timestamp: u64) -> Vec<TxHash> ⓘ

Drain all expired keys and return the transaction hashes that should be evicted.

Keys with expiry <= tip_timestamp are considered expired.
