• Constants
• Variables
• type Channel
• func NewChannel() *Channel
• func NewChannelWithSize(bufSize int) *Channel
• func (cwt *Channel) Receive() (interface{}, error)
• func (cwt *Channel) Send(value interface{})
• func (cwt *Channel) TimedReceive(timeout time.Duration) (interface{}, error)

Constants ¶

const (
	// DefaultChanRecvTimeout is the default timeout for receive operations on the
	// underlying channel.
	DefaultChanRecvTimeout = 1 * time.Second
	// DefaultChanBufferSize is the default buffer size of the underlying channel.
	DefaultChanBufferSize = 1
)

Variables ¶

var ErrRecvTimeout = errors.New("timed out when waiting for value on channel")

ErrRecvTimeout is an error to indicate that a receive operation on the channel timed out.

Types ¶

type Channel ¶

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

Channel wraps a generic channel and provides a timed receive operation.

func NewChannel ¶

func NewChannel() *Channel

NewChannel returns a new Channel.

func NewChannelWithSize ¶

func NewChannelWithSize(bufSize int) *Channel

NewChannelWithSize returns a new Channel with a buffer of bufSize.

func (*Channel) Receive ¶

func (cwt *Channel) Receive() (interface{}, error)

Receive returns the value received on the underlying channel, or ErrRecvTimeout if DefaultChanRecvTimeout amount of time elapses.

func (*Channel) Send ¶

func (cwt *Channel) Send(value interface{})

Send sends value on the underlying channel.

func (*Channel) TimedReceive ¶

func (cwt *Channel) TimedReceive(timeout time.Duration) (interface{}, error)

TimedReceive returns the value received on the underlying channel, or ErrRecvTimeout if timeout amount of time elapsed.
