Functions ¶

func Equal ¶

func Equal(u1 UUID, u2 UUID) bool

Equal returns true if u1 and u2 equals, otherwise returns false.

Types ¶

type UUID ¶

type UUID [16]byte

UUID representation compliant with specification described in RFC 4122.

func And ¶

func And(u1 UUID, u2 UUID) UUID

And returns result of binary AND of two UUIDs.

func FromBytes ¶

func FromBytes(input []byte) (u UUID, err error)

FromBytes returns UUID converted from raw byte slice input. It will return error if the slice isn't 16 bytes long.

func FromString ¶

func FromString(input string) (u UUID, err error)

FromString returns UUID parsed from string input. Following formats are supported: "6ba7b810-9dad-11d1-80b4-00c04fd430c8", "{6ba7b810-9dad-11d1-80b4-00c04fd430c8}", "urn:uuid:6ba7b810-9dad-11d1-80b4-00c04fd430c8"

func NewV1 ¶

func NewV1() UUID

NewV1 returns UUID based on current timestamp and MAC address.

func NewV2 ¶

func NewV2(domain byte) UUID

NewV2 returns DCE Security UUID based on POSIX UID/GID.

func NewV3 ¶

func NewV3(ns UUID, name string) UUID

NewV3 returns UUID based on MD5 hash of namespace UUID and name.

func NewV4 ¶

func NewV4() UUID

NewV4 returns random generated UUID.

func NewV5 ¶

func NewV5(ns UUID, name string) UUID

NewV5 returns UUID based on SHA-1 hash of namespace UUID and name.

func Or ¶

func Or(u1 UUID, u2 UUID) UUID

Or returns result of binary OR of two UUIDs.

func (UUID) Bytes ¶

func (u UUID) Bytes() []byte

Bytes returns bytes slice representation of UUID.

func (UUID) MarshalBinary ¶

func (u UUID) MarshalBinary() (data []byte, err error)

MarshalBinary implements the encoding.BinaryMarshaler interface.

func (UUID) MarshalText ¶

func (u UUID) MarshalText() (text []byte, err error)

MarshalText implements the encoding.TextMarshaler interface. The encoding is the same as returned by String.

func (*UUID) SetVariant ¶

func (u *UUID) SetVariant()

SetVariant sets variant bits as described in RFC 4122.

func (*UUID) SetVersion ¶

func (u *UUID) SetVersion(v byte)

SetVersion sets version bits.

func (UUID) String ¶

func (u UUID) String() string

Returns canonical string representation of UUID: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx.

func (UUID) StringMd5 ¶

func (u UUID) StringMd5() string

func (UUID) StringTrim ¶

func (u UUID) StringTrim() string

func (*UUID) UnmarshalBinary ¶

func (u *UUID) UnmarshalBinary(data []byte) error

UnmarshalBinary implements the encoding.BinaryUnmarshaler interface.

func (*UUID) UnmarshalText ¶

func (u *UUID) UnmarshalText(text []byte) error

UnmarshalText implements the encoding.TextUnmarshaler interface. UUID is expected in a form accepted by FromString.

func (UUID) Variant ¶

func (u UUID) Variant() uint

Variant returns UUID layout variant.

func (UUID) Version ¶

func (u UUID) Version() uint

Version returns algorithm version used to generate UUID.
