Derive

The compiler is capable of providing basic implementations for some traits via the #[derive] attribute. These traits can still be manually implemented if a more complex behavior is required.

The following is a list of derivable traits:

• Comparison traits: Eq, PartialEq, Ord, PartialOrd.
• Clone, to create T from &T via a copy.
• Copy, to give a type 'copy semantics' instead of 'move semantics'.
• Hash, to compute a hash from &T.
• Default, to create an empty instance of a data type.
• Debug, to format a value using the {:?} formatter.
