Traits

Note: this section is still under development, who knows if it’ll exist in the future

#todo

Traits are essentially Rust’s version of interfaces.

trait Hello {
  fn say_hello(&self) {
  }
}

Trait objects

• what can be turned into an object?
  • why does having a method without &self mean you can’t turn it into an object?
• when should or shouldn’t you use boxed trait objects?
  • Don’t Use Boxed Trait Objects for Struct Internals
