Follow the steps to implement this recipe:

1. Open the main.rs file in the src directory in your preferred text editor.
2. Write the code header with the relevant information:

        //-- #########################
        //-- Task: File system experiments
        //-- Author: Vigneshwer.D
        //-- Version: 1.0.0
        //-- Date: 04 May 17
        //-- ######################### 

3. Create the error_chain! macro to define a custom Error and Result type, along with automatic conversions from the standard library error types, after the code header:

        #[macro_use]
        extern crate error_chain;
        use std::fs::File;
        use std::io::{Write, BufReader, BufRead};
        error_chain! {
          foreign_links {
            Io(std::io::Error);
          }
        }

4. Define the run method and the quick_main! macro by copying and pasting the following code snippet with the error_chain! macro:

        fn run() -> Result<()> {
          let path = "lines.txt";
          let mut output = File::create(path)?;
          write!(output, "Rust
is
Fun")?;
          let input = File::open(path)?;
          let buffered = BufReader::new(input);
          for line in buffered.lines() {
            println!("{}", line?);
          }
          Ok(())
        }
        quick_main!(run);

5. Save the file and run the project by running the command:

      cargo run

We should get the following output on execution of the code:
