events
Instructions
You have to design a notification system for a platform.
These events can be: Remainders, Registrations, Appointments or Holidays.
-
Create an event handler that, depending on the type of event, creates different notifications with different colors, different sizes and different positions
-
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 beYou 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
Expected Functions and Data Structures
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.
use events::Event::*;
use chrono::Duration;
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
