rustrust string bytes

A Rust String is a UTF-8 encoded sequence of bytes. It is a collection of u8 values, and is stored as a vector of bytes (Vec<u8>).

let s = String::from("Hello world!");
let bytes = s.as_bytes();

The output of the above code is [72, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100, 33].

Code explanation

• let s = String::from("Hello world!");: This creates a String from the given string literal.
• let bytes = s.as_bytes();: This creates a Vec<u8> from the String, containing the UTF-8 encoded bytes of the string.
