Fields

level: u16

Numeric level (1-based, 0 = no save active).

save_id: u32

Unique save id for invalidation tracking.

records: Vec<SaveRecord>

COW records accumulated during this save level.

valid: bool

Whether this save level is still valid (becomes false on restore).

d_stack_depth: usize

Snapshot of d_stack length at save time (for restore validation).

packing_mode: bool

Saved packing mode (setpacking/currentpacking).

vm_alloc_mode: bool

Saved VM allocation mode (setglobal/currentglobal).

object_format: i32

Saved binary object format (setobjectformat/currentobjectformat).

gstate: GraphicsState

Saved graphics state and graphics state stack.

gstate_stack: Vec<GstateEntry>
