I've just started to teach myself Rust. I've written the following code to read a text file and store the contents in a String. Is this the typical way of doing this? Can anyone suggest any improvements to this?use std::fs::File;use std::io::Read;use std::io;fn main() {    let file_name = test.txt;    let mut file_contents = String::new();    match get_file_contents(file_name, &mut file_contents) {        Ok(()) => (),        Err(err) => panic!({}, err)    };    println!({}, file_contents);}fn get_file_contents(name: &str, mut contents: &mut String) -> Result<(), io::Error> {    let mut f = try!(File::open(name));    try!(f.read_to_string(&mut contents));    Ok(())}
Read file contents to string safely
strings;io;rust
You could return the string directly:fn main() {    let file_name = test.txt;    let file_contents = match get_file_contents(file_name) {        Ok(s) => s,        Err(err) => panic!({}, err)    };    println!({}, file_contents);}fn get_file_contents(name: &str) -> Result<String, io::Error> {    let mut f = try!(File::open(name));    let mut contents = String::new();    try!(f.read_to_string(&mut contents));    Ok(contents)}and unwrap if you dont intend to handle the error usefully:let file_contents = get_file_contents(file_name).unwrap();
