memory property
Memory is the card's VRAM as its own tooling reported it ("122880 MiB") — a display string in the reporter's units, not a byte count. BYO cards carry it (nvidia-smi); Visor's machine object states no VRAM, so a rented card leaves it empty and the console renders "—" rather than a fabricated 0.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
String? memory;
