How to apply a function to each element of a vector in Rust (analog of map)?

Hello colleagues! I just started learning Rust, switched from Python, and I have a problem with processing vectors. In Python I used to do this: ```python numbers = [1, 2, 3, 4] squared = list(map(lambda x: x**2, numbers)) # [1, 4, 9, 16] ``` Or using list comprehension, which is even more convenient. In Rust I wrote something like this: ```rust fn main() { let numbers = vec![1, 2, 3, 4]; // I want to get a new vector with squares of numbers let squared: Vec = numbers.map(|x| x * x).collect(); println!("{:?}", squared); } ``` The compiler gives an error: ``` error[E0599]: no method named `map` found for struct `Vec` in the current scope ``` I understand that Rust is not Python, and everything is stricter with types here. But how do I process each element of a vector?
