In the following code, I rightfully get a panic that crashes the program.
How would I handle the error in this case so the app can show a dialog and log the error without the app crashing?
pub fn main() {
let mut white_pos_tuple_vec: Vec<(f64, f64)> = Vec::new();
white_pos_tuple_vec.push((4.0, 5.0));
white_pos_tuple_vec.push((5.0, 6.0));
white_pos_tuple_vec.push((7.0, 8.0));
white_pos_tuple_vec.push((9.0, 10.0));
let index = white_pos_tuple_vec
.iter()
.position(|&x| x.0 == 7.0 && x.1 == 9.0)
.unwrap();
println!("{}", index);
println!("Index value of tuple = {:?}", white_pos_tuple_vec[index]);
}
