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 aStringfrom the given string literal.let bytes = s.as_bytes();: This creates aVec<u8>from theString, containing the UTF-8 encoded bytes of the string.
