Types

type Buffer

type Buffer struct {
	sync.RWMutex
	// contains filtered or unexported fields
}

Buffer is ring buffer

func New

func New(i int) *Buffer

New returns a new buffer of the given size

func (*Buffer) Get

func (b *Buffer) Get(n int) []*Entry

Get returns the last n entries

func (*Buffer) Put

func (b *Buffer) Put(v interface{})

Put adds a new value to ring buffer

func (*Buffer) Since

func (b *Buffer) Since(t time.Time) []*Entry

Return the entries since a specific time

func (*Buffer) Size

func (b *Buffer) Size() int

Size returns the size of the ring buffer

func (*Buffer) Stream

func (b *Buffer) Stream(stop chan bool) <-chan *Entry

Stream logs from the buffer

type Entry

type Entry struct {
	Value     interface{}
	Timestamp time.Time
}

Entry is ring buffer data entry
