A Ring is a fixed size circular buffer.
The capacity of a buffer is always rounded up to the nearest power of 2 for optimal performance.
r := ring.New[int](2)
r.Put(0, 42)
r.Put(1, 555)
fmt.Println(r.Get(0))
fmt.Println(r.Get(1))
fmt.Println(r.Get(2))
fmt.Println(r.Get(3))
fmt.Println(r.Get(4))Output:
42
555
