//! Fast Object Lock System
|
|
//!
|
|
//! High-performance versioned object locking system optimized for object storage scenarios
|
|
//!
|
|
//! ## Core Features
|
|
//!
|
|
//! 1. **Sharded Architecture** - Hash-based object key sharding to avoid global lock contention
|
|
//! 2. **Version Awareness** - Support for multi-version object locking with fine-grained control
|
|
//! 3. **Fast Path** - Lock-free fast paths for common operations
|
|
//! 4. **Async Optimized** - True async locks that avoid thread blocking
|
|
//! 5. **Auto Cleanup** - Access-time based automatic lock reclamation
