To create and manipulate a circular buffer (ring) in Go using the container/ring
package, follow these steps:
container/ring
package:import "container/ring"
size := 5
myRing := ring.New(size)
Do()
method to iterate over the ring and assign values:myRing.Do(func(p interface{}) {
myRing.Value = 0 // Assign initial value to the ring
myRing = myRing.Next()
})
Value
field to get or set the value at the current position:current := myRing.Value.(int) // Get the value at current position
myRing.Value = current + 1 // Set the value at current position
Next()
and Prev()
methods:myRing = myRing.Next() // Move to the next element
myRing = myRing.Prev() // Move to the previous element
Do()
method. For example, to print all the values in the ring:myRing.Do(func(p interface{}) {
fmt.Println(p)
myRing = myRing.Next()
})
