Here i have skipped 7 line but now i want to get result from that result which i have skipped. I want to get 1st line from it but i can not get it then how can i get this first line?

#1

use std::fs::File;

use std::io::{Write, BufReader, BufRead};

use std::io;

fn main() {

run();

}

fn run() -> Result<(), io::Error> {

let path = "hosts.txt";

let mut output = File::create(path)?;

write! (output, "host, Ip

##

# Host Database

#

# localhost is used to configure the loopback interface

# when the system is booting.  Do not change this entry.

##

127.0.0.1 localhost

255.255.255.255   broadcast host

::1  localhost")?;

let input = File::open(path)?;

let buffered = BufReader::new(input);

for line in buffered.lines().skip(7  ) {   // I need to skip the first line of the file

    let record = line?;

    println!("{:#?}", record);

    let mut dog = String::new();

    record::stdin().read_line(&mut dog).unwrap();

    println!("Hello {}!", dog);

    let data: Vec<&str> = record.split_whitespace().collect();
}
Ok(())

}

#2 
let buffered_lines = buffered.lines();
let first_line = buffered_lines.next().unwrap();

for line in buffered_lines.skip(7) {
    // …
}

Is that what you want? I'm not entirely sure, I understood your question and the comment in the code.

I have done this but now I want the first line from that obtained part.

#4

et buffered = BufReader::new(input);

for line in buffered.lines().skip(7  ) {   

  
    let record = line?;

   

    println!("{:#?}", record);

    println!("{:#?}", first_line);

}

I have done this
