Probably, this cannot throw error because it all things needs to be handled within Rust and we cannot cross the FFI boundary.

Lines 83 to 87 in 0f0bbc0

    
           pub(crate) fn extract_self_from_altrep<T>(x: &SEXP) -> &mut T { 
        
               let x = unsafe { crate::get_external_pointer_addr(R_altrep_data1(*x)).unwrap() as *mut T }; 
        
               let self_ = unsafe { x.as_mut() }; 
        
               self_.expect("Failed to convert the external pointer to the Rust object") 
        
           }
