read file in rusr

To read a file in Rust, you can use the std::fs::read_to_string function to read the contents of a file into a string. Here's an example:

use std::fs;

fn main() {
    let file_contents = fs::read_to_string("path/to/file.txt").expect("Failed to read file");
    println!("{}", file_contents);
}

In this example, path/to/file.txt should be replaced with the actual path to the file you want to read. The read_to_string function returns a Result<String, std::io::Error>, so you can use the expect method to handle any potential errors that may occur during the file reading process.

Please note that you need to have the necessary permissions to read the file, and the file should exist at the specified path.
