FromString parses a UUID string in the format "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" and returns a UUIDv5 structure.

Parameters:

• uuidStr: A string containing the UUID in the format "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"

Returns:

• An error if the UUID is invalid or the conversion fails

func (*UUIDv5) Marshal

func (u *UUIDv5) Marshal() ([]byte, error)

Marshal converts the UUIDv5 structure to a 16-byte array

Returns:

• A byte slice containing the UUID's 16 bytes
• An error if the UUID is invalid or the conversion fails

func (*UUIDv5) String

func (u *UUIDv5) String() string

String returns the string representation of the UUIDv5 structure

Returns:

• The string representation of the UUIDv5 structure

func (*UUIDv5) Unmarshal

func (u *UUIDv5) Unmarshal(marshalledData []byte) (int, error)

Unmarshal converts a 16-byte array into a UUIDv5 structure
