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(())
}
