Types

type Counter

type Counter struct {
	// contains filtered or unexported fields
}

    Counter is a rolling counter that increments an index up to a maximum value. If the counter reaches the maximum then the counter resets to 0. A single counter instance may be used by multiple Go routines.

    func New

    func New() *Counter

      New returns a new rolling counter

      func (*Counter) Next

      func (c *Counter) Next(n int) int

        Next increments the counter. If the counter reaches n then the counter is reset to 0. Note: n must be greater than 0 or else a panic will result.
