NewReader returns a new Reader reading from b.

func (*Reader) Len 

func (r *Reader) Len() int

Len returns the number of bytes of the unread portion of the slice.

Seek implements the io.Seeker interface.

func (*Reader) Size 

func (r *Reader) Size() int64

Size returns the original length of the underlying byte slice. Size is the number of bytes available for reading via ReadAt. The returned value is always the same and is not affected by calls to any other method.

WriteTo implements the io.WriterTo interface.

type RingBuffer 

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

RingBuffer is a MPMC buffer that achieves threadsafety with CAS operations only. A put on full or get on empty call will block until an item is put or retrieved. Calling Dispose on the RingBuffer will unblock any blocked threads with an error. This buffer is similar to the buffer described here: http://www.1024cores.net/home/lock-free-algorithms/queues/bounded-mpmc-queue with some minor additions.

func NewRingBuffer 

func NewRingBuffer(size uint64) *RingBuffer

NewRingBuffer will allocate, initialize, and return a ring buffer with the specified size.

func (*RingBuffer) Cap 

func (rb *RingBuffer) Cap() uint64

Cap returns the capacity of this ring buffer.

func (*RingBuffer) Dispose 

func (rb *RingBuffer) Dispose()

Dispose will dispose of this queue and free any blocked threads in the Put and/or Get methods. Calling those methods on a disposed queue will return an error.

func (*RingBuffer) Get 

func (rb *RingBuffer) Get() (interface{}, error)

Get will return the next item in the queue. This call will block if the queue is empty. This call will unblock when an item is added to the queue or Dispose is called on the queue. An error will be returned if the queue is disposed.

func (*RingBuffer) IsDisposed 

func (rb *RingBuffer) IsDisposed() bool

IsDisposed will return a bool indicating if this queue has been disposed.

func (*RingBuffer) Len 

func (rb *RingBuffer) Len() uint64

Len returns the number of items in the queue.

func (*RingBuffer) Offer 

func (rb *RingBuffer) Offer(item interface{}) (bool, error)

Offer adds the provided item to the queue if there is space. If the queue is full, this call will return false. An error will be returned if the queue is disposed.

func (*RingBuffer) Put 

func (rb *RingBuffer) Put(item interface{}) error

Put adds the provided item to the queue. If the queue is full, this call will block until an item is added to the queue or Dispose is called on the queue. An error will be returned if the queue is disposed.

type SkipHash 

type SkipHash struct {
	hash.Hash32
	// contains filtered or unexported fields
}

func (*SkipHash) Write 

func (self *SkipHash) Write(p []byte) (n int, err error)
