Implementations

impl Locks

fn new(
    ts: TimeStamp,
    hash: u64,
    key: Vec<u8>,
    resource_group_tag: Vec<u8>,
    last_detect_time: Instant
) -> Self

Creates a new Locks.

fn push(&mut self, lock_hash: u64, key: Vec<u8>, now: Instant)

Pushes the hash if not exist and updates last_detect_time.

fn remove(&mut self, lock_hash: u64) -> bool

Removes the lock_hash and returns true if the Locks is empty.

fn is_expired(&self, now: Instant, ttl: Duration) -> bool

Returns true if the Locks is expired.

fn to_wait_for_entry(&self, waiter_ts: TimeStamp) -> WaitForEntry

Generate a WaitForEntry for the lock.
