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: page.rs
    path of file: ./repos/aero/src/aero_kernel/src/mem/paging
    
    the code of the file until where you have to start completion: // Copyright (C) 2021-2024 The Aero Project Deve
    
    pub fn as_slice_mut<T>(&self) -> &mut [T] {
        assert!(core::mem::size_of::<T>() < S::SIZE as usize);

        let virt = self.start_address().as_hhdm_virt();
        let ptr = virt.as_mut_ptr::<T>();

        // SAFETY: The size of the slice is equal to the size of the frame and the
        // pointer is valid.
        unsafe {
            core::slice::from_raw_parts_mut(ptr, S::SIZE as usize / core::mem::size_of::<T>())
        }
    }
