Implementations

impl Lock

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

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

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

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

fn pre_allocate_size(&self) -> usize

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

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

pub fn check_ts_conflict(
    lock: Cow<'_, Self>,
    key: &Key,
    ts: TimeStamp,
    bypass_locks: &TsSet
) -> Result<()>

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

Trait Implementations

impl Clone for Lock

fn clone(&self) -> Lock

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Lock

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl PartialEq<Lock> for Lock

fn eq(&self, other: &Lock) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Lock) -> bool

This method tests for !=.
