# Gzip Compression Tool

This Rust program compresses a file using gzip compression. It takes two command line arguments: the source file and the destination file.

## Usage

```bash

cargo run  

```

## Example

```bash

cargo run input.txt output.gz

```

## Code

```rust

extern crate flate2;

use flate2::write::GzEncoder;

use flate2::Compression;

use std::env::args;

use std::fs::File;

use std::io::copy;

use std::io::BufReader;

use std::time::Instant;

fn main() {

    if args().len() != 3 {

        eprintln!("Usage: {}  ", args().nth(0).unwrap());

        return;

    }

    let mut input = BufReader::new(File::open(args().nth(1).unwrap()).unwrap());

    let output = File::create(args().nth(2).unwrap()).unwrap();

    let mut encoder = GzEncoder::new(output, Compression::default());

    let start = Instant::now();

    copy(&mut input, &mut encoder).unwrap();

    println!(

        "Compressed {} bytes in {} ms",

        input.get_ref().metadata().unwrap().len(),

        start.elapsed().as_millis(),

    );

}

```
