You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: from_raw_arc.rs
    path of file: ./repos/krustlet/crates/kubelet/src/mio_uds_windows/sys/windows
    
    the code of the file until where you have to start completion: //! A "Manual Arc" which allows manually frobbing the reference count
//!
//! This module contains a copy of the `Arc` found in the standard library,
//
    
    fn drops() {
        struct A<'a>(&'a mut bool);
        impl<'a> Drop for A<'a> {
            fn drop(&mut self) {
                *self.0 = true;
            }
        }
        let mut a = false;
        {
            let a = FromRawArc::new(A(&mut a));
            let _ = a.clone();
            assert!(!*a.0);
        }
        assert!(a);
    }
