我想在 `main()` 之外的模块中启动 Rocket 但失败了

Question

我想在 main() 之外的模块中启动 Rocket，这样可以简化 main() 但我失败了。我从 rocket

代码：

mod myRocket {
    #![feature(plugin)]
    #![plugin(rocket_codegen)]
    extern crate rocket;

    #[get("/")]
    fn index() -> &'static str {
        "Hello, world!"
    }

    pub fn startup() {
        rocket::ignite().mount("/", routes![index]).launch();
    }
}


fn main() {
    myRocket::startup();
}

错误：

error: cannot find macro `routes!` in this scope
--> src\main.rs:12:37
|
12 |         rocket::ignite().mount("/", routes![index]).launch();
|

我不知道怎么解决。

Answer 1

我做到了。我项目的箱子是 rocket_demo

main.rs

extern crate rocket_demo; 

use rocket_demo::my_rocket;

fn main() {
    my_rocket::startup();
}

lib.rs

#![feature(plugin)]
#![plugin(rocket_codegen)]
extern crate rocket;

pub mod my_rocket;

前三行不能在my_rocket/mod.rs，否则routes!找不到！

my_rocket/mod.rs

#[get("/")]
fn index() -> &'static str {
    "Hello, world!"
}

pub fn startup() {
    ::rocket::ignite().mount("/", routes![index]).launch();
}

我想在 `main()` 之外的模块中启动 Rocket 但失败了

I want to start Rocket in a module out of `main()` but failed
