Functions

func Decode

func Decode(id string) ([16]byte, error)

Decode parses a 26-char ULID string into its 16 raw bytes.

func New

func New(ms uint64) (string, error)

New generates a ULID for the given millisecond timestamp with random entropy.

func NewWithEntropy

func NewWithEntropy(ms uint64, entropy []byte) (string, error)

NewWithEntropy generates a ULID deterministically from ms and 10-byte entropy.

func Timestamp

func Timestamp(id string) (uint64, error)

Timestamp decodes the millisecond timestamp encoded in a ULID string.
