Must Be The Same Type

TODO: Put in note earlier about calling the branches arms

Using an if/else expression to determine a variable to bind directly to a variable requires both the if arm and the else arm to provide the same type. So you can have two i32 values like this:

let alfa = true;
let bravo = if alfa { 1 } else { 0 };

or two bool values like this:

let alfa = true;
let bravo = if alfa { true } else { false };

but you can't mix them like this which will give an error:

SOURCE CODE

fn main() {
  let alfa = true;
  let bravo = if true { 1 } else { false };

  println!("bravo is {bravo}");
}
