Now that we know a little bit about trait objects and how to work with them, let's use them in a different example, this challenge focuses on using Box<dyn Trait> as fields in structs to encapsulate objects with dynamic behavior.

You need to define a trait called Renderable and create two structs, Circle and Rectangle, that implement this trait. Then, you will create another struct called Canvas, which can hold a collection of objects implementing the Renderable trait. The Canvas struct should have methods to add objects and render all objects.

Here are the requirements for the program, make sure to read them carefully:

• The trait should have a method render(&self) -> String to represent the object visually.

• Circle should have a radius: f64 field.
• Rectangle should have width: f64 and height: f64 fields.

• For Circle, the render method should return a string like "Circle with radius X".
• For Rectangle, the render method should return a string like "Rectangle with width X and height Y".

• The struct should have a shapes field that can store a Vec of the Renderable trait objects.
• Implement the following methods for Canvas:
  • new() -> Canvas: Initializes an empty canvas.
  • add_shape(): Adds a shape to the canvas.
  • render_all(): Returns a vector of strings, each representing a rendered shape.

⚠️ Make sure you make all the relevant items public with the pub keyword, this is required for the tests to work.

If you're stuck, here are some hints to help you solve the challenge:
