## events
### Instructions
You're have to design a notification system for a platform
This events can be: Remainders, Registrations, Appointments or Holidays
- Create an event handler that depending of the type of event creates different notification: different color, different size and different position
- The possible positions are Top, Bottom and Center: Create and Enum `Position` with those values
- Create a method called `notify` which returns a notification with the following caracteristics for each
- Remainder:
size= 50,
color= (50, 50, 50),
position= Bottom,
content= the slice associated to the enum value
- Registration(chrono::Duration),
size = 30,
color = (255, 2, 22),
position = Top,
content = "You have `duration` left before the registration ends",
`durations` must be displayed in the form of {hours}:{minutes}:{seconds} left for the beginning of the event for example if there is two hours 32 minutes and 3 seconds left before the registration then the content will be `You have 2:32:2 left before the registration ends`
- Appointment(text)
size: 100
color: (200, 200, 3)
position: Center
content: text associated to the value
- Holiday
size: 25
color: (0, 255, 0)
position: Top
content: "Enjoy your holiday"
- Implement the std::fmt::Display trait so the text of the notification is printed in the right color in the command line
### Notions
- https://docs.rs/colored/2.0.0/colored/
### Expected Functions and Data Structures
```rust
use chrono::Duration;
use colored::*;
#[derive(Debug, Eq, PartialEq)]
enum Position {
Top,
Bottom,
Center,
}
#[derive(Debug, Eq, PartialEq)]
struct Notification {
size: u32,
color: (u8, u8, u8),
position: Position,
content: String,
}
#[derive(Debug)]
enum Event<'a> {
Remainder(&'a str),
Registration(Duration),
Appointment(&'a str),
Holiday,
}
use std::fmt;
impl fmt::Display for Notification {
}
use Event::*;
impl Event {
fn notify(&self) -> Notification {
}
}
```
### Usage
Here is a program to test your function.
```rust
fn main() {
let remainder = Remainder("Go to the doctor");
println!("{}", remainder.notify());
let registration = Registration(Duration::seconds(49094));
println!("{}", registration.notify());
let appointment = Appointment("Go to the doctor");
println!("{}", appointment.notify());
let holiday = Holiday;
println!("{}", holiday.notify());
}
```
And its output
```console
student@ubuntu:~/[[ROOT]]/test$ cargo run
(Bottom, 50, Go to the doctor)
(Top, 30, You have 13H:38M:14S left before the registration ends)
(Center, 100, Go to the doctor)
(Top, 25, Enjoy your holiday)
student@ubuntu:~/[[ROOT]]/test$
```
