How to split file? or is it Recommend?

[shinriyo]

Hi there.

I always document write source code in main.rs.

original file tree

• src/main.rc

So, I split program the program in main.rs

    let mut server = Nickel::new();
    let mut router = Nickel::router();
    let conn = Connection::connect("postgres://postgres@localhost", SslMode::None).unwrap();
    let shared_connection = Arc::new(Mutex::<Connection>::new(conn));

    {
        let conn = shared_connection.clone();
        router.get("/api/movies", middleware! { |_, mut response|
            let conn = conn.lock().unwrap();
    // Do something

my purpose

path tree

• src/main.rc
• src/movie/mod.rs

mod movie; // module reading

fn main() {
    let mut server = Nickel::new();
    let mut router = Nickel::router();
    let conn = Connection::connect("postgres://postgres@localhost", SslMode::None).unwrap();
    movie::url(conn, router);

and

pub fn url(conn:Connection, mut router:Router) {
    let shared_connection = Arc::new(Mutex::<Connection>::new(conn));

    {
        let conn = shared_connection.clone();
        router.get("/api/movies", middleware! { |_, mut response|

However, the error occurred.

use of moved value: `router`

splitting source code does not recommend?
I just want to set argument in url method.
Could you help me?

Hi @shinriyo,

I think the signature you're looking for is:

pub fn url(shared_connection: Arc<Mutex<Connection>>, router: &mut Router) {
        router.get("/api/movies", middleware! { |_, mut response|

Note the use of &mut Router instead of Router to prevent the 'use of moved value' error.

The usage from main.rs would then become:

fn main() {
    let mut server = Nickel::new();
    let mut router = Nickel::router();
    let conn = Connection::connect("postgres://postgres@localhost", SslMode::None).unwrap();
    let shared_connection = Arc::new(Mutex::new(conn));
    movie::url(shared_connection.clone(), &mut router);

Thank you for replying.
Wow! Thank you very much! Your submit code worked with no problem!
