Struct PendingStalenessTracker

Source

struct PendingStalenessTracker {
    previous_pending: HashSet<TxHash>,
    last_snapshot_time: Option<u64>,
    interval_secs: u64,
}

Expand description

Tracks pending transactions across snapshots to detect stale transactions.

Uses a simple snapshot comparison approach:

Every interval, take a snapshot of current pending transactions
Transactions present in both the previous and current snapshot are considered stale
Stale transactions are evicted since they’ve been pending for at least one full interval

Fields§

§previous_pending: HashSet<TxHash>

Previous snapshot of pending transaction hashes.

§last_snapshot_time: Option<u64>

Timestamp of the last snapshot.

§interval_secs: u64

Interval in seconds between staleness checks.

Implementations§

Source §

impl PendingStalenessTracker

Source

fn new(interval_secs: u64) -> Self

Creates a new tracker with the given check interval.

Source

fn should_check(&self, now: u64) -> bool

Returns true if the staleness check interval has elapsed and a snapshot should be taken.

Source

fn check_and_update( &mut self, current_pending: HashSet<TxHash>, now: u64, ) -> Vec<TxHash> ⓘ

Checks for stale transactions and updates the snapshot.

Returns transactions that have been pending across two consecutive snapshots (i.e., pending for at least one full interval).

Call should_check first to avoid collecting the pending set on every block.
