Sort Vector of Tuples in Rust

sort-vec-of-tuples.rs

fn main() {
  let mut v: Vec<(&str, i32)> = vec![("a", 2), ("b", 1), ("c", 3)];
  v.sort_by(|a, b| a.1.cmp(&b.1)); // increasing order
  v.sort_by(|a, b| b.1.cmp(&a.1)); // decreasing order
  println!("{:?}", v);
}

Hi @mehmetsefabalik,
How do you sort tuples vector if contents inside tuple is being changed to some option struct? For example,

struct Car {price: f64}

let mut v: Vec<(&str, Option<Car>)> = vec![
    ("a", Some(Car {price: 3.2})),
    ("b", Some(Car {price: 2.2})),
    ("c", Some(Car {price: 23.2}))
];
