+ | <code rust> | ||
+ | impl Summary for SomeStruct { | ||
+ | fn summarize(& | ||
+ | //some code | ||
+ | } | ||

+ | </ | ||
+ | |||
+ | If the trait had a default behavior, this implementation will override it. | ||
+ | |||
+ | Default implementations can also call other methods in the same trait, even if those other methods don't have a default implementation. | ||
