The byte values operator.
When you are dealing with string literials:
let my_string = "hello world";Sometimes we need to tell Rust that the string should be treated as a series of bytes. Why? Lots of built-in functions require string values as a series of bytes.
The way this is done, is by putting the letter 'b' before the string literal, like this:
let my_string = b"hello world";Bingo. The string will be interpreted as a series of bytes, rather than as a string literal.
