My own minimalist Go library that generates uuid's that implement v4, variant 10.

Securely uses crypto/rand for random number generation.

Using this library instead of typical uuid libraries (that package other uuid versions/features) can reduce a compiled binary size by as much as 7% according to my experiments.

First, get it:

go get -v github.com/charles-m-knox/go-uuid

Now, in a main.go file:

package main

import (
    "log"

    uuid "github.com/charles-m-knox/go-uuid"
)

func main() {
    u := uuid.New() // generates the uuid
    log.Println(u)  // prints the uuid to console
}

You can also check out uuid_test.go to see the unit tests.
