Functions

func KeyValues

func KeyValues(space uuid.UUID, m map[string]string) uuid.UUID

KeyValues produces a UUID for the given key-value map in the suppied name space.

Example

package main

import (
	"fmt"

	"github.com/google/uuid"

	"github.com/mmcloughlin/cb/app/id"
)

func main() {
	space := uuid.MustParse("19433b12-5b85-4252-9bb0-594a38156713")
	ident := id.KeyValues(space, map[string]string{"greeting": "hello", "who": "world"})
	fmt.Println(ident)
}

Output:

60376fde-597e-5694-8a19-e6dd930fbec0

func Strings

func Strings(space uuid.UUID, s []string) uuid.UUID

Strings produces a UUID for the given list of strings in the suppied name space.

Example

package main

import (
	"fmt"

	"github.com/google/uuid"

	"github.com/mmcloughlin/cb/app/id"
)

func main() {
	space := uuid.MustParse("19433b12-5b85-4252-9bb0-594a38156713")
	ident := id.Strings(space, []string{"hello", "world"})
	fmt.Println(ident)
}

Output:

func UUID

func UUID(space uuid.UUID, data []byte) uuid.UUID

UUID generates a UUIDv5 from the given data.

Example

package main

import (
	"fmt"

	"github.com/google/uuid"

	"github.com/mmcloughlin/cb/app/id"
)

func main() {
	space := uuid.MustParse("19433b12-5b85-4252-9bb0-594a38156713")
	ident := id.UUID(space, []byte("hello world"))
	fmt.Println(ident)
}
