pub unsafe fn R_PreserveObject(object: SEXP)Expand description
Add a SEXP to the global precious list, preventing GC indefinitely.
Cost: O(1) but allocates a CONSXP cell — creates GC pressure on every
call. The precious list is a global linked list (R_PreciousList).
Use only for long-lived objects (e.g., ExternalPtr stored across R calls).
For temporary protection within a function, prefer Rf_protect.
Checked wrapper for R_PreserveObject. Calls R_PreserveObject_unchecked and routes through with_r_thread.
