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 createT
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.
