This package provides pure Go implementation of Universally Unique Identifier (UUID). Supported both creation and parsing of UUIDs.
With 100% test coverage and benchmarks out of box.
Supported versions:
- Version 1, based on timestamp and MAC address (RFC 4122)
- Version 2, based on timestamp, MAC address and POSIX UID/GID (DCE 1.1)
- Version 3, based on MD5 hashing (RFC 4122)
- Version 4, based on random numbers (RFC 4122)
- Version 5, based on SHA-1 hashing (RFC 4122)
Use the go command:
$ go get github.com/satori/go.uuid
UUID package requires Go >= 1.2.
package main
import (
"fmt"
"github.com/satori/go.uuid"
)
func main() {
// Creating UUID Version 4
// panic on error
u1 := uuid.Must(uuid.NewV4())
fmt.Printf("UUIDv4: %s\n", u1)
// or error handling
u2, err := uuid.NewV4()
if err != nil {
fmt.Printf("Something went wrong: %s", err)
return
}
fmt.Printf("UUIDv4: %s\n", u2)
// Parsing UUID from string input
u2, err := uuid.FromString("6ba7b810-9dad-11d1-80b4-00c04fd430c8")
if err != nil {
fmt.Printf("Something went wrong: %s", err)
}
fmt.Printf("Successfully parsed: %s", u2)
