Public Member Functions
	RepUID (const ::occtl_rep_uid_t theUid) noexcept
	Wraps an existing C value type (zero-cost).

::occtl_rep_uid_t	get () const noexcept
	Borrows-it view of the underlying C value type, for direct ABI calls.

std::array< std::uint8_t, OCCTL_REP_UID_WIRE_SIZE >	to_bytes () const
	Encodes this RepUID into the fixed-width C wire format.

bool	is_valid () const noexcept
	True when the UID is not the all-zero sentinel.

bool	operator== (const RepUID &theOther) const noexcept
	Bitwise equality.

bool	operator!= (const RepUID &theOther) const noexcept
	Bitwise inequality.

Static Public Member Functions
static RepUID	invalid () noexcept
	Returns the invalid sentinel (all-zero bits).

static RepUID	from_bytes (const std::array< std::uint8_t, OCCTL_REP_UID_WIRE_SIZE > &theBytes)
	Decodes a RepUID from the fixed-width C wire format.

Detailed Description

Persistent identity surviving representation removal and graph compaction.

Use occtl::Graph::rep_id_from_rep_uid to resolve back to a RepId. The all-zero value (OCCTL_REP_UID_INVALID) is the invalid sentinel.
