Types

type ArtifactServer 

type ArtifactServer struct {

type MuxConn added in v0.5.0 

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

MuxConn is able to multiplex multiple streams on top of any io.ReadWriteCloser. These streams act like TCP connections (Dial, Accept, Close, full duplex, etc.).

The underlying io.ReadWriteCloser is expected to guarantee delivery and ordering, such as TCP. Congestion control and such aren't implemented by the streams, so that is also up to the underlying connection.

MuxConn works using a fairly dumb multiplexing technique of simply framing every piece of data sent into a prefix + data format. Streams are established using a subset of the TCP protocol. Only a subset is necessary since we assume ordering on the underlying RWC.

Create a new MuxConn around any io.ReadWriteCloser.

func (*MuxConn) Accept added in v0.5.0

func (*MuxConn) Close added in v0.5.0 

func (m *MuxConn) Close() error

Close closes the underlying io.ReadWriteCloser. This will also close all streams that are open.

func (*MuxConn) Dial added in v0.5.0 

func (m *MuxConn) Dial(id uint32) (io.ReadWriteCloser, error)

Dial opens a connection to the remote end using the given stream ID. An Accept on the remote end will only work with if the IDs match.

func (*MuxConn) NextId added in v0.5.0 

func (m *MuxConn) NextId() uint32

NextId returns the next available listen stream ID that isn't currently taken.
