Types

type Ring 

type Ring struct {
	// contains filtered or unexported fields

Ring represents a container/ring with seperate reader and writer interfaces. It will only read non-nil values and will overwrite the oldest values on subsequent Write()'s. Originally designed as a FIFO packet buffer.

func NewRing 

func NewRing(size int) *Ring

Return a new Ring with the specified capactiy.

func (*Ring) Read 

func (r *Ring) Read() interface{}

Read the next value from the ring. If the value is nil, we will sit here until there is a non-nil value to return, then advance for the next Read().

func (r *Ring) Write(value interface{})

Write the value to the Ring. Write's will always succeed and will overwrite the oldest elements in the Ring first.
