rustHow to convert a Rust slice to a string?

To convert a Rust slice to a String, you can use the String::from_utf8 method. This method takes a &[u8] slice and returns a Result<String, FromUtf8Error>.

Example code

let slice = [104, 101, 108, 108, 111];
let string = String::from_utf8(slice).unwrap();
println!("{}", string);

Output example

hello

Code explanation

• let slice = [104, 101, 108, 108, 111];: This creates a &[u8] slice containing the ASCII values for the characters h, e, l, l, and o.
• let string = String::from_utf8(slice).unwrap();: This calls the String::from_utf8 method on the slice variable, which returns a Result<String, FromUtf8Error>. The unwrap method is used to get the String from the Result.
• println!("{}", string);: This prints the String to the console.
