Read A File Into A String In Rust

The basic approach is to use:

Code

use std::fs;

let data = fs::read_to_string("some/path.txt").unwrap();

An `.unwrap()`rust` is used because `read_to_string()`rust` returns a Result. The above works if you're sure the file won't cause an error or you're okay with a panic if it does. Basic error handling can be used when that's not the case:

Code

use std::fs;

let data = fs::read_to_string(
    "some/path.txt",
);

match data {
    Ok(value) => println!("{}", value),
    Err(e) => println!("{}", e),
}
