A Go library providing wrapper types for primitive types that enforce atomic access, offering a safer and more convenient API than the standard library's sync/atomic package. It preserves all sync/atomic functionality while making it harder to accidentally access variables non-atomically.

Use cases

• safely share counters across goroutines
• enforce atomic access to primitive variables in Go
• replace error-prone sync/atomic usage with type-safe wrappers
• implement lock-free counters and flags
• avoid data races on shared numeric state

When to choose

• you need atomic operations on primitives in Go and want compile-time safety
• your team struggles with remembering which variables require atomic access
• you want convenient methods like Store, Add, and CompareAndSwap on typed values

When to avoid

• you only need simple mutex-protected state and prefer standard library only
• you need atomic operations on complex structs rather than primitives
• you are not writing Go
