pub unsafe extern "C-unwind" fn R_PreserveObject_unchecked(
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.
Unchecked FFI binding for R_PreserveObject.
