Rust/Statement

• main thing is that statements get semicolons.
• it's possible to have something which doesn't compile because the last line in the function actually has or doesn't have a semicolon.
  • It needs to have a semicolon if the last line is a statement.
  • It needs to NOT have a semicolon if the last line is a Rust/Expression.

      fn main() {
          let x = plus_one(5);
      
          println!("The value of x is: {x}");
      }
      
      fn plus_one(x: i32) -> i32 {
          x + 1; // <- will not compile
      }
