How do I display a HTML webpage by file name in Rocket?

I am able to make a HTML webpage but only with the content directly in my .rs file.

use rocket::*;
use rocket::response::content::RawHtml;

#[get("/")]
fn index() -> RawHtml<&'static str> {
    RawHtml(r#"<h1>Hello world</h1>"#)
}

#[launch]
fn rocket() -> _ {
    rocket::build().mount("/", routes![index])
}

How do I separate it giving a link to the file to be displayed to Rocket?

If you want the HTML document compiled in to your program so that it has no dependencies on external files, you can use the standard include_str! macro:

RawHtml(include_str!("index.html"))

This will look for index.html in the same directory as the .rs file the macro appears in during compilation, and insert the contents as a static string literal.

Alternatively, if you want the program to look for a file on disk at runtime, you can use Rocket's NamedFile responder.
