How do I generate a text file during compile time and include its content in the output?

Question

I\'m trying to do almost the same as How to create a static string at compile time.

build.rs

use std::{env};
use std::path::Path;
use std::io::{Wri

The trick was

concat!(env!("OUT_DIR"), "/file_path.txt")

I changed my main.rs as follows and it worked.

fn main() {

    static LONG_STRING: &'static str = include_str!(concat!(env!("OUT_DIR"), "/file_path.txt"));

    println!("{}", LONG_STRING);
}

The following crates.io documentation helped
