Functions ¶

func BothClosed ¶

func BothClosed(in *Inbound, out *Outbound) (closed bool)

Types ¶

type Circular ¶

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

A circular buffer on top of a byte-array NOTE: It does not implement the Write() method, it implements ReadFrom() to avoid copies

func NewCircular ¶

func NewCircular(size int) *Circular

Returns a new circular buffer of the given size

func (*Circular) Read ¶

func (c *Circular) Read(p []byte) (n int, err error)

Read data out of the buffer. This never fails but may return n==0 if there is no data to be read

func (*Circular) ReadFrom ¶

func (c *Circular) ReadFrom(rd io.Reader) (n int, err error)

Copy data from the given reader into the buffer Any errors encountered while reading are returned EXCEPT io.EOF. If the reader fills the buffer, it returns buffer.FullError

type Inbound ¶

type Inbound struct {
	*Circular
	*sync.Cond
	// contains filtered or unexported fields
}

func NewInbound ¶

func NewInbound(size int) *Inbound

func (*Inbound) GetError ¶

func (b *Inbound) GetError() (err error)

func (*Inbound) Read ¶

func (b *Inbound) Read(p []byte) (n int, err error)

func (*Inbound) ReadFrom ¶

func (b *Inbound) ReadFrom(rd io.Reader) (n int, err error)

func (*Inbound) SetDeadline ¶

func (b *Inbound) SetDeadline(t time.Time)

func (*Inbound) SetError ¶

func (b *Inbound) SetError(err error)

type Outbound ¶

type Outbound struct {
	*sync.Cond
	// contains filtered or unexported fields
}

func NewOutbound ¶

func NewOutbound(size int) *Outbound

func (*Outbound) Decrement ¶

func (b *Outbound) Decrement(dec int) (ret int, err error)

func (*Outbound) Increment ¶

func (b *Outbound) Increment(inc int)

func (*Outbound) SetError ¶

func (b *Outbound) SetError(err error)
