## vehicles

### Instructions

- Create the trait Vehicle with the model and year

- In a border cross you want to keep a list of all the vehicles that are waiting to enter the country. You want to keep a waiting list of the vehicle but the vehicles can be of two types: Car or Truck

- Create a function that receives a vector of structures that implements the Vehicle trait and returns all the models.

With the following structure:

### Expected Functions and Structures

```rust
#[allow(dead_code)]
pub struct Car<'a> {
	pub plate_nbr: &'a str,
	pub model: &'a str,
	pub horse_power: u32,
	pub year: u32,
}

#[allow(dead_code)]
pub struct Truck<'a> {
	pub plate_nbr: &'a str,
	pub model: &'a str,
	pub horse_power: u32,
	pub year: u32,
	pub load_tons: u32,
}

pub trait Vehicle {
	fn model(&self) -> &str;
	fn year(&self) -> u32;
}

impl Vehicle for Truck<'_> {
}

impl Vehicle for Car<'_> {
}

fn all_models(list: Vec<&Vehicle>) -> Vec<&str> {
}
```

### Usage

Here is a program to test your function.

```rust
fn main() {
	let vehicles: Vec<&dyn Vehicle> = vec![
		&Car {
			plate_nbr: "A3D5C7",
			model: "Model 3",
			horse_power: 325,
			year: 2010,
		},
		&Truck {
			plate_nbr: "V3D5CT",
			model: "Ranger",
			horse_power: 325,
			year: 2010,
			load_tons: 40,
		},
	];
	println!("{:?}", all_models(vehicles));
}
```

And its output

```console
student@ubuntu:~/vehicles/test$ cargo run
["Model 3", "Ranger"]
student@ubuntu:~/vehicles/test$
```
