Package atomic provides simple wrappers around numerics to enforce atomic access.
Code:
// Uint32 is a thin wrapper around the primitive uint32 type. var atom atomic.Uint32 // The wrapper ensures that all operations are atomic. atom.Store(42) fmt.Println(atom.Inc()) fmt.Println(atom.CAS(43, 0)) fmt.Println(atom.Load())
Output:
43 true 0
