CDERIVABLE TRAITS

In various places in the book, we’ve discussed the derive attribute, which you can apply to a struct or enum definition. The derive attribute generates code that will implement a trait with its own default implementation on the type you’ve annotated with the derive syntax.

In this appendix, we provide a reference of all the traits in the standard library that you can use with derive. Each section covers:

• What operators and methods deriving this trait will enable
• What the implementation of the trait provided by derive does
• What implementing the trait signifies about the type
• The conditions in which you’re allowed or not allowed ...
