Function find 

pub fn find<T, F>(collection: &[T], predicate: F) -> Option<&T>
where
    F: Fn(&T) -> bool,

Find the first item in a collection that satisfies a predicate. If no item satisfies the predicate, return None.

Arguments

• collection - A collection of items.
• predicate - A function that takes an item from the collection and returns a boolean.

Returns

• Some(&T) - The first item in the collection that satisfies the predicate.
• None - If no item satisfies the predicate.

Examples

use lowdash::find;
let numbers = vec![1, 2, 3, 4, 5];
let predicate = |x: &i32| *x == 3;
let result = find(&numbers, predicate);
assert_eq!(result, Some(&3));

use lowdash::find;
let numbers = vec![10, 20, 30, 40];
let result = find(&numbers, |x| *x > 25);
assert_eq!(result, Some(&30));

let result = find(&people, |p| p.age > 30);
