Functions ¶

func Listen ¶

func Listen(network, addr string) (net.Listener, error)

Listen returns TCP listener with SO_REUSEADDR option set, SO_REUSEPORT is not supported on Windows, so it uses SO_REUSEADDR as an alternative to achieve the same effect.

package main

import (
	"fmt"
	"log"

	"github.com/valyala/fasthttp"
	"github.com/valyala/fasthttp/reuseport"
)

func main() {
	ln, err := reuseport.Listen("tcp4", "localhost:12345")
	if err != nil {
		log.Fatalf("error in reuseport listener: %v", err)
	}

	if err = fasthttp.Serve(ln, requestHandler); err != nil {
		log.Fatalf("error in fasthttp Server: %v", err)
	}
}

func requestHandler(ctx *fasthttp.RequestCtx) {
	fmt.Fprintf(ctx, "Hello, world!")
}

Types ¶

type ErrNoReusePort ¶

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

ErrNoReusePort is returned if the OS doesn't support SO_REUSEPORT.

func (*ErrNoReusePort) Error ¶

func (e *ErrNoReusePort) Error() string

Error implements error interface.
