More Notes on Rust Strings

I spent some time today continuing my VERY slow study about Rust.

Misc tip: .into() is a method for casting in Rust
String type is defined in the Rust standard library (std), and is stored as a vector of bytes (Vec)
- It’s guaranteed to always be a valid UTF-8 sequence
- It’s growable and NOT null-terminated
Use the String.push_str() method when mutating / pushing more characters onto an existing String
- Note: Use the String.push() method when pushing a single char into an existing String
- You can also use the += syntax to push characters onto an existing String

fn main() {
  let mut S: String = String::from("hello");
  s.push(',');
  s.push_str(" world");
  s += "!";
}
