where
    T: Clone + Default,

Returns the last item from the collection. If the collection is empty, returns the default value of T and false.

Returns

• (T, bool) - A tuple containing the last item and true. If the collection is empty, returns (T::default(), false).

Examples

use lowdash::last;

let numbers = vec![1, 2, 3];
let (last_num, exists) = last(&numbers);
assert_eq!(last_num, 3);
assert!(exists);

let empty: Vec<i32> = vec![];
let (last_num, exists) = last(&empty);
assert_eq!(last_num, 0); // i32::default() is 0
assert!(!exists);

use lowdash::last;

#[derive(Debug, PartialEq, Clone, Default)]
struct Person {
    name: String,
    age: u32,
}

let people = vec![
    Person { name: "Alice".to_string(), age: 25 },
    Person { name: "Bob".to_string(), age: 30 },
];

let (last_person, exists) = last(&people);
assert_eq!(last_person, Person { name: "Bob".to_string(), age: 30 });
assert!(exists);

let empty_people: Vec<Person> = vec![];
let (last_person, exists) = last(&empty_people);
assert_eq!(last_person, Person::default());
assert!(!exists);
