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: date_and_time.rs
    path of file: ./repos/diesel/diesel_tests/tests/expressions
    
    the code of the file until where you have to start completion: use crate::schema::*;
#[cfg(feature = "postgres")]
use diesel::data_types::*;
use diesel::dsl::*;
use diesel::sql_types::Nullable;
use diesel::*;

table! {
    has_timestamps {
        id -> Integer,
        created
    
fn time_is_deserialized_properly() {
    use self::has_time::dsl::*;

    let connection = &mut connection();
    setup_test_table(connection);
    diesel::sql_query(
        "INSERT INTO has_time (\"time\") VALUES
                       ('00:00:01'), ('00:02:00'), ('03:00:00')
                       ",
    )
    .execute(connection)
    .unwrap();
    let one_second = PgTime(1_000_000);
    let two_minutes = PgTime(120_000_000);
    let three_hours = PgTime(10_800_000_000);
    let expected_data = vec![one_second, two_minutes, three_hours];

    let actual_data = has_time.select(time).load(connection);
    assert_eq!(Ok(expected_data), actual_data);
}
