Object Oriented Programming

OOP

Compréhension

• （）

  ： Objects Contain Data and Behavior

  ： Encapsulation that Hides Implementation Details

  ：typepartagé Inheritance as a Type System and as Code Sharing

• trait object

  Box trait object，Rust ， ——

  pub trait Draw {
      fn draw(&self);
  }
  // trait object
  pub struct Screen {
      pub components: Vec<Box<dyn Draw>>,
  }
  impl Screen {
      pub fn run(&self) {
          for component in self.components.iter() {
              component.draw();
          }
      }
  }
  // generic type + trait buond
  pub struct Screen<T: Draw> {
      pub components: Vec<T>,
  }
  impl<T> Screen<T>
  where
      T: Draw,
  {
      pub fn run(&self) {
          for component in self.components.iter() {
              component.draw();
          }
