Types

type Error

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

func NewError

func NewError(info string) *Error

func (*Error) Base

func (e *Error) Base(err error) *Error

func (*Error) Error

func (e *Error) Error() string

type Notifier

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

Notifier is a utility for notifying changes. The change producer may notify changes multiple time, and the consumer may get notified asynchronously.

func NewNotifier

func NewNotifier() *Notifier

NewNotifier creates a new Notifier.

func (*Notifier) Signal

func (n *Notifier) Signal()

Signal signals a change, usually by producer. This method never blocks.

func (*Notifier) Wait

func (n *Notifier) Wait() <-chan struct{}

Wait returns a channel for waiting for changes. The returned channel never gets closed.

type RewindConn

type RewindConn struct {
	net.Conn
	*RewindReader
}

func NewRewindConn

func NewRewindConn(conn net.Conn) *RewindConn

func (*RewindConn) Read

func (c *RewindConn) Read(p []byte) (int, error)

type RewindReader

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

func (*RewindReader) Discard

func (r *RewindReader) Discard(n int) (int, error)

func (*RewindReader) Read

func (r *RewindReader) Read(p []byte) (int, error)

func (*RewindReader) ReadByte

func (r *RewindReader) ReadByte() (byte, error)

func (*RewindReader) Rewind

func (r *RewindReader) Rewind()

func (*RewindReader) SetBufferSize

func (r *RewindReader) SetBufferSize(size int)

func (*RewindReader) StopBuffering

func (r *RewindReader) StopBuffering()

type Runnable

type Runnable interface {
	Run() error
	Close() error
}

type StickyWriter

type StickyWriter struct {
	MaxBuffered int
	// contains filtered or unexported fields
}

func (*StickyWriter) Write

func (w *StickyWriter) Write(p []byte) (int, error)
