Implementations

impl Lock[−]

pub fn new(
    lock_type: LockType,
    primary: Vec<u8, Global>,
    ts: TimeStamp,
    ttl: u64,
    short_value: Option<Vec<u8, Global>>,
    for_update_ts: TimeStamp,
    txn_size: u64,
    min_commit_ts: TimeStamp
) -> Lock

pub fn use_async_commit(self, secondaries: Vec<Vec<u8, Global>, Global>) -> Lock

pub fn with_rollback_ts(self, rollback_ts: Vec<TimeStamp, Global>) -> Lock

pub fn to_bytes(&self) -> Vec<u8, Global>

pub fn parse(b: &[u8]) -> Result<Lock, Error>

pub fn into_lock_info(self, raw_key: Vec<u8, Global>) -> LockInfo

pub fn check_ts_conflict(
    lock: Cow<'_, Lock>,
    key: &Key,
    ts: TimeStamp,
    bypass_locks: &TsSet
) -> Result<(), Error>[−]

Checks whether the lock conflicts with the given ts. If ts == TimeStamp::max(), the primary lock will be ignored.
