feat: introduce TTL support with ExpiringCache decorator#132
Merged
Conversation
- Added time-based expiration functionality through the `Expiring<C>` decorator, allowing caches to manage per-entry TTLs. - Implemented `Clock` trait and `MockClock` for time management, enabling deterministic testing. - Introduced `ExpirationIndex` for efficient deadline tracking and management of expired entries. - Updated `CacheBuilder` to support `DynExpiringCache` with default TTL configuration. - Added benchmarks to evaluate the overhead of the TTL decorator against a standard LRU cache. This implementation enhances the cache library's capabilities by allowing for more flexible cache management strategies, particularly in scenarios requiring time-based expiration.
- Updated doc comments in `builder.rs` to accurately reference the `CacheBuilder` module. - Refined documentation in `expiration_index.rs` to enhance clarity regarding the `LazyMinHeap` wrapper. - Adjusted comments in `expiring.rs` to simplify the description of ordering enforcement in the `purge_one` method. These changes improve the accuracy and readability of the documentation, ensuring users have a clearer understanding of the cache library's components and their interactions.
