cmap

Partitions the map into segments to minimize lock contention, improving performance in high-concurrency scenarios as shown in benchmarks for operations like adversarial alloc and delete.

Provides atomic Store, Load, and Delete methods safe for concurrent use, addressing the built-in map's limitation without data races, similar to sync.Map but with sharding.

Offers a type-safe cmap.Map for Go 1.18+, enhancing code clarity and reducing runtime type assertions, as demonstrated in the README's generics example.

Benchmarks indicate strong results in write-heavy and adversarial scenarios, outperforming sync.Map in tests like LoadOrStoreUnique and adversarial delete.

Mirrors the interface of standard Go maps and sync.Map with intuitive methods, making adoption straightforward, as seen in the usage examples.
