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: slice_from_raw.rs
    path of file: ./repos/kani/tests/kani/Slice
    
    the code of the file until where you have to start completion: // Copyright Kani Contributors

fn main() {
    let address = 0x01234usize;
    let r = address as *mut i32;
    let slice: &mut [i32] = unsafe { slice::from_raw_parts_mut(r, 10000) };
    // the behavior is undefined when the slice is used
    slice[9999] = 0; // verification succeeds
    assert!(slice[9999] == 0); // verification succeeds
}
