Expand description

Interval-based range lock manager

Uses an interval tree for O(log n) conflict detection.

Implementations§

Source §

impl RangeLockManager

Source

pub fn new() -> Self

Source

pub fn acquire( &self, txn_id: TxnId, range: KeyRange, is_write: bool, ) -> Result<(), RangeLockConflict>

Source

pub fn check_conflict( &self, txn_id: TxnId, range: &KeyRange, is_write: bool, ) -> Option<TxnId>

Check for conflicts without acquiring

Source

pub fn lock_count(&self, txn_id: TxnId) -> usize

Get number of locks held by a transaction
