Types

type UUID

type UUID struct {
	TimeLow            uint32
	TimeMid            uint16
	TimeHighAndVersion uint16
	ClockAndVariant    uint16
	Node               []byte
}

func NewUUID

func NewUUID(version int, args map[string]string) (*UUID, error)

Creates a new UUID. Custom namespaces must be a valid string representation of an UUID.

The accepted args keys/values are:

[variant]:
	microsoft | dce | future
[name]:
	valid string
[namespace]:
	dns | url | oid | x500 | custom

func (*UUID) Stringify

func (uuid *UUID) Stringify() string

Serialize an UUID to a hex string representation.
