Tuple Indexes

Getting values out of a tuple is done using the variable's name followed by a dot and the "index" number for the position we're after.

For example:

alfa.2

The index position represents a counter that starts at the beginning of the tuple and goes up one for each position. But, the first number is zero instead of one. So, the first position is 0, the second position is 1, etc...

Here's an example creating a tuple that holds an i32, a f32, and a bool and then prints them out.

SOURCE CODE

fn main() {

  let alfa: (i32, f32, bool) = (99, 234.5, false);

  println!("1st {}", alfa.0);
  println!("2nd {}", alfa.1);
  println!("3rd {}", alfa.2);

}
