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: preview1_clock_time_get.rs
    path of file: ./repos/wasmtime/crates/test-programs/src/bin
    
    the code of the file until where you have to start completion: unsafe fn test_clock_time_get() {
    // Test that clock_time_get succeeds. Even in environments where it's not
    // desirable to expose high-precision timers, it should still succeed.
    // clock_res_get is where information about precision can be provided.
    wasi::clock_time_get(wasi::CLOCKID_MONOTONIC, 1).expect("precision 1 should work");

    let first_time =

    
unsafe fn test_clock_time_get() {
    // Test that clock_time_get succeeds. Even in environments where it's not
    // desirable to expose high-precision timers, it should still succeed.
    // clock_res_get is where information about precision can be provided.
    wasi::clock_time_get(wasi::CLOCKID_MONOTONIC, 1).expect("precision 1 should work");

    let first_time =
        wasi::clock_time_get(wasi::CLOCKID_MONOTONIC, 0).expect("precision 0 should work");

    let time = wasi::clock_time_get(wasi::CLOCKID_MONOTONIC, 0).expect("re-fetch time should work");
    assert!(first_time <= time, "CLOCK_MONOTONIC should be monotonic");
}
