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: test_flex_array_members.rs
    path of file: ./repos/c2rust/tests/structs/src
    
    the code of the file until where you have to start completion: use crate::flex_array_members::rust_exercise_flex_arrays;
use libc::{c_int, c_uint, size_t};

#[link(name = "test")]
extern "C" {
    fn exercise_flex_arrays(_: c_uint, _: *mut c_int);

    
pub fn test_flex_array_members() {
    let mut buffer = [0; BUFFER_SIZE];
    let mut rust_buffer = [0; BUFFER_SIZE];
    let expected_buffer = [0, 0, 0, 10, 0, 0, 0, 10, 0, 0, 0, 15];

    unsafe {
        exercise_flex_arrays(BUFFER_SIZE as u32, buffer.as_mut_ptr());
        rust_exercise_flex_arrays(BUFFER_SIZE as u32, rust_buffer.as_mut_ptr());
    }

    assert_eq!(buffer, rust_buffer);
    assert_eq!(buffer, expected_buffer);
}
