rustrust string as bytes

A Rust String can be converted to a Vec<u8> of bytes using the as_bytes() method. This method returns a &[u8] slice, which can be converted to a Vec<u8> using the to_vec() method.

Example

let my_string = String::from("Hello World!");
let bytes = my_string.as_bytes().to_vec();

Output example

[72, 101, 108, 108, 111, 32, 87, 111, 114, 108, 100, 33]

Code explanation

• my_string: a String containing the text "Hello World!"
• as_bytes(): a method that returns a &[u8] slice of the bytes of the String
• to_vec(): a method that converts a &[u8] slice to a Vec<u8>
