Functions

func EpollCtl

func EpollCtl(epfd, op, fd int, event *EpollEvent) (errno syscall.Errno)

func EpollWait

func EpollWait(epfd int, events []EpollEvent, maxev, waitms int) (int, syscall.Errno)

func Open

func Open(r reactor.Conn) error

func Register

func Register()

Types

type BaseConn

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

func NewBaseConn

func NewBaseConn(
	conn io.ReadWriteCloser,
	onread reactor.Reader,
	ondisconnect reactor.Disconnector,
) (*BaseConn, error)

func (*BaseConn) Close

func (b *BaseConn) Close() error

Close closes the connection. Any blocked Read or Write operations will be unblocked and return errors.

func (*BaseConn) FD

func (b *BaseConn) FD() int

func (*BaseConn) LocalAddr

func (b *BaseConn) LocalAddr() net.Addr

LocalAddr returns the local network address, if known.

func (*BaseConn) OnDisconnect

func (b *BaseConn) OnDisconnect(buf []byte, err error)

func (*BaseConn) OnRead

func (b *BaseConn) OnRead(buf []byte)

func (*BaseConn) Pin

func (b *BaseConn) Pin() bool

func (*BaseConn) Read

func (b *BaseConn) Read(buf []byte) (n int, err error)

Unimplemented

func (*BaseConn) RemoteAddr

func (b *BaseConn) RemoteAddr() net.Addr

RemoteAddr returns the remote network address, if known.

func (*BaseConn) SetDeadline

func (b *BaseConn) SetDeadline(t time.Time) error

SetDeadline sets the read and write deadlines associated with the connection. It is equivalent to calling both SetReadDeadline and SetWriteDeadline.

A deadline is an absolute time after which I/O operations fail instead of blocking. The deadline applies to all future and pending I/O, not just the immediately following call to Read or Write. After a deadline has been exceeded, the connection can be refreshed by setting a deadline in the future.

If the deadline is exceeded a call to Read or Write or to other I/O methods will return an error that wraps os.ErrDeadlineExceeded. This can be tested using errors.Is(err, os.ErrDeadlineExceeded). The error's Timeout method will return true, but note that there are other possible errors for which the Timeout method will return true even if the deadline has not been exceeded.

An idle timeout can be implemented by repeatedly extending the deadline after successful Read or Write calls.

A zero value for t means I/O operations will not time out.

func (*BaseConn) SetNextReadSize

func (b *BaseConn) SetNextReadSize(n int)

func (*BaseConn) SetPoller

func (b *BaseConn) SetPoller(pd reactor.Poller)

func (*BaseConn) SetReadDeadline

func (b *BaseConn) SetReadDeadline(t time.Time) error

SetReadDeadline sets the deadline for future Read calls and any currently-blocked Read call. A zero value for t means Read will not time out.

func (*BaseConn) SetWriteDeadline

func (b *BaseConn) SetWriteDeadline(t time.Time) error

SetWriteDeadline sets the deadline for future Write calls and any currently-blocked Write call. Even if write times out, it may return n > 0, indicating that some of the data was successfully written. A zero value for t means Write will not time out.

func (*BaseConn) Unpin

func (b *BaseConn) Unpin() bool

func (*BaseConn) Write

func (b *BaseConn) Write(buf []byte) (n int, err error)

Write writes data to the connection. Write can be made to time out and return an error after a fixed time limit; see SetDeadline and SetWriteDeadline.

func (*BaseConn) WriteBuffer

func (b *BaseConn) WriteBuffer(buf []byte) (n int, pb *buffer.PendingBuffer, err error)

For wrapper

type EpollEvent

type EpollEvent struct {
	Events uint32
	Data   [8]byte // unaligned uintptr
}
