go-stream-muxer - generalized stream multiplexing

go-stream-muxer is a common interface for stream muxers, with common tests. It wraps other stream muxers (like muxado, spdystream and yamux).

A test suite and interface you can use to implement a stream muxer.

Implementations

Badge

Include this badge in your readme if you make a new module that uses abstract-stream-muxer API.

Installation

go get -d github.com/jbenet/go-stream-muxer
cd $GOPATH/src/github.com/jbenet/go-stream-muxer
make deps

Client example

import (
  "net"
  "fmt"
  "io"
  ymux "github.com/jbenet/go-stream-muxer/yamux"
  smux "github.com/jbenet/go-stream-muxer"
)

func dial() {
  nconn, _ := net.Dial("tcp", "localhost:1234")
  sconn, _ := ymux.DefaultTransport.NewConn(nconn, false) // false == client

  go sconn.Serve(func(smux.Stream) {}) // no-op

  s1, _ := sconn.OpenStream()
  s1.Write([]byte("hello"))

  s2, _ := sconn.OpenStream()
  s2.Write([]byte("world"))

  length := 20
  buf2 := make([]byte, length)
  fmt.Printf("reading %d bytes from stream (echoed)\n", length)

  s1.Read(buf2)

  fmt.Printf("received %s as a response\n", string(buf2))

  s3, _ := sconn.OpenStream()
  io.Copy(s3, os.Stdin)
}

Server example

import (
  "net"
  "fmt"
  "io"
  ymux "github.com/jbenet/go-stream-muxer/yamux"
  smux "github.com/jbenet/go-stream-muxer"
)

func listen() {
  tr := ymux.DefaultTransport
  l, _ := net.Listen("tcp", "localhost:1234")

  go func() {
    for {
      c, _ := l.Accept()

      fmt.Println("accepted connection")
      sc, _ := tr.NewConn(c, true)

      go sc.Serve(func(s smux.Stream) {
        fmt.Println("serving connection")
        echoStream(s)
      })
    }
  }()
}

func echoStream(s smux.Stream) {
  defer s.Close()

  fmt.Println("accepted stream")
  io.Copy(s, s) // echo everything
  fmt.Println("closing stream")
}
