Types

type Generator

type Generator interface {
	NextV4() UUID
	NextV7() UUID
}

Generator is something that can generate UUIDs

var DefaultGenerator Generator = defaultGenerator{}

DefaultGenerator is the default generator for calls to NewUUID

func NewSeededGenerator

func NewSeededGenerator(seed int64, now dates.NowFunc) Generator

NewSeededGenerator creates a new UUID generator that uses the given seed for the random component and the time source for the time component (only applies to v7)

type UUID
