Public Member Functions
	EZ_DECLARE_POD_TYPE ()
EZ_ALWAYS_INLINE	ezUuid ()=default
	Default constructor. Constructed Uuid will be invalid.
EZ_ALWAYS_INLINE constexpr	ezUuid (ezUInt64 uiLow, ezUInt64 uiHigh)
	Constructs the Uuid from existing values.
EZ_ALWAYS_INLINE bool	operator== (const ezUuid &other) const
	Comparison operator. [tested].
EZ_ALWAYS_INLINE bool	operator!= (const ezUuid &other) const
	Comparison operator. [tested].
EZ_ALWAYS_INLINE bool	operator< (const ezUuid &other) const
	Comparison operator.
EZ_ALWAYS_INLINE bool	IsValid () const
	Returns true if this is a valid Uuid.
void	GetValues (ezUInt64 &ref_uiLow, ezUInt64 &ref_uiHigh) const
	Returns the internal 128 Bit of data.
EZ_ALWAYS_INLINE void	CombineWithSeed (const ezUuid &seed)
	Adds the given seed value to this guid, creating a new guid. The process is reversible.
EZ_ALWAYS_INLINE void	RevertCombinationWithSeed (const ezUuid &seed)
	Subtracts the given seed from this guid, restoring the original guid.
EZ_ALWAYS_INLINE void	HashCombine (const ezUuid &hash)
	Combines two guids using hashing, irreversible and order dependent.

Static Public Member Functions
static EZ_ALWAYS_INLINE ezUuid	MakeInvalid ()
	Returns an invalid UUID.
static ezUuid	MakeUuid ()
	Returns a new Uuid.
static ezUuid	MakeStableUuidFromString (ezStringView sString)
	Creates a uuid from a string. The result is always the same for the same string.
static ezUuid	MakeStableUuidFromInt (ezInt64 iInt)
	Creates a uuid from an integer. The result is always the same for the same input.

Friends
EZ_FOUNDATION_DLL_FRIEND void	operator>> (ezStreamReader &inout_stream, ezUuid &ref_value)
	Operator to serialize ezUuid objects. [tested].
EZ_FOUNDATION_DLL_FRIEND void	operator<< (ezStreamWriter &inout_stream, const ezUuid &value)
	Operator to serialize ezUuid objects. [tested].

Detailed Description

128-bit Universally Unique Identifier (UUID/GUID) for object identification and referencing.

ezUuid provides a robust way to uniquely identify objects, assets, or entities across systems, time, and network boundaries. It's essential for serialization, asset management, networking, and any scenario where objects need stable, globally unique identities.
