About

Go programming language (http://golang.org/) bindings for radix tree library for fast subnet (both IPv4 and IPv6) lookups.

Installing

$ go get github.com/thekvs/go-net-radix

After this command go-net-radix library is ready to use and will be located in:

$GOROOT/src/pkg/github.com/thekvs/go-net-radix

Basic usage example

package main

import (
        "github.com/thekvs/go-net-radix"

        "fmt"
        "log"
)

func main() {
        rtree, err := netradix.NewNetRadixTree()
        if err != nil {
                panic(err)
        }
        defer rtree.Close()

        if err = rtree.Add("217.72.192.0/20", "UDATA1"); err != nil {
                log.Fatal(err)
        }

        if err = rtree.Add("2001:220::/35", "UDATA2"); err != nil {
                log.Fatal(err)
        }

        var found bool
        var udata string

        found, udata, err = rtree.SearchBest("217.72.192.2")
        if err != nil {
                log.Fatal(err)
        }
        if found {
                fmt.Printf("found: %v\n", udata)
        }

        found, udata, err = rtree.SearchBest("2001:220::")
        if err != nil {
                log.Fatal(err)
        }
        if found {
                fmt.Printf("found: %v\n", udata)
        }

        if err = rtree.Remove("217.72.192.0/20"); err != nil {
                log.Fatal(err)
        }
}
