This UUID library is an yet another attempt to reimplement the wheel, but instead of outstanding algorithm it wraps the Linux kernel implementation of UUID v4 generator.

The latest version can be installed using go tool:

go get github.com/ybubnov/go-uuid

The usage is pretty straightforward. Here is the most trivial example:

package main

import (
    "fmt"

    "github.com/ybubnov/go-uuid"
)

func main() {
    u1 := uuid.New()
    fmt.Printf("uuid v4: %s\n", u1)
}

Another example shows an advanced configuration of generator. It defines the 128 buffered UUIDs, and 16 workers used to produce them.

package main

import (
    "fmt"

    "github.com/ybubnov/go-uuid"
)

func main() {
    src := uuid.Kernel{MaxIdle: 128, MaxProcs: 16}
    defer src.Stop() // Terminate source when time comes.

    u1, err := src.Next()
    if err != nil {
        fmt.Printf("failed to generate uuid: %s\n", err)
    }

    fmt.Printf("uuid v4: %s\n", u1)
}
