Accepts the following formats: 00000000-0000-0000-0000-000000000000 {00000000-0000-0000-0000-000000000000} urn:uuid:00000000-0000-0000-0000-000000000000

Parameters:

uuidStr – string to try and convert to Uuid from

inline Uuid(carb::cpp::unbounded_string uuidStr) noexcept

Convert a string to a Uuid using UUID format.

Accepts the following formats: 00000000-0000-0000-0000-000000000000 {00000000-0000-0000-0000-000000000000} urn:uuid:00000000-0000-0000-0000-000000000000

Parameters:

uuidStr – string to try and convert to Uuid from

inline Uuid &operator=(carb::cpp::string_view uuidStr) noexcept

Assignment operator from string.

Accepts the same formats as the constructor.

Parameters:

uuidStr – string to parse and assign from

Returns:

reference to this Uuid

inline bool isEmpty() const noexcept

Check if Uuid is empty.

Returns:

true if Uuid is empty; otherwise, false

inline const value_type &data() const noexcept

Access the binary data of the UUID.

Returns:

array of UUID data

inline bool operator==(const Uuid &rhs) const noexcept

Compare two UUIDs for equality.

Parameters:

rhs – right hand side of ==

Returns:

true if uuids are equal; otherwise false

inline bool operator!=(const Uuid &rhs) const noexcept

Compare two UUIDs for inequality.

Parameters:

rhs – right hand side of !=

Returns:

true if uuids are not equal; otherwise false
