ark::core::Guid

Defined in header “ark/core/guid.hh”.

---

A class that represents a GUID. This GUID is stored as a 16-byte array and is automatically parsed (or converted) into a human readable string form on demand.

Methods

• Guid()
  Default constructor. Produces an empty (null) GUID.

• Guid(const std::string_view & value)
  Initializes a GUID from the given string. It is assumed that the string is in the form of XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX.

• Guid(uint64_t first_half, uint64_t second_half)
  Initializes a GUID from two halves of a 128-bit integer.

• Guid(const uint8_t * data)
  Initializes a GUID from the raw byte array. It is assumed that this array is 128-bits (16 bytes).

• constexpr Guid(std::array< uint8_t, 16 > data)
  Initializes a GUID from the given array.

• constexpr Guid(const Guid & other)
  Initializes a GUID from a copy of the given GUID.

• constexpr Guid & operator=(const Guid & other)
  Copy operator. Defines to support constexpr initialization.

• bool null()
  Returns true if this is an empty (null) GUID.

• std::string str()
  Returns a string representation of the given GUID, in the form of XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX.

• const uint8_t * data()
  Returns the raw byte data of this GUID.

• constexpr bool operator==(const Guid & other)
  Equality operator.

• constexpr bool operator!=(const Guid & other)
  Non-equality operator.

• constexpr auto operator(const Guid & other)
  Spaceship operator, for remaining comparisons.
