12 trait Merge {
13     fn merge(&mut self, other: Self);
17 `Merge` is implemented for `Option` and can be derived for structs:
19 <!-- should be kept in sync with examples/user.rs -->
21 use merge::Merge;
23 #[derive(Merge)]
25     // Fields with the skip attribute are skipped by Merge
26     #[merge(skip)]
29     // The Merge implementation for Option replaces its value if it is None
32     // The strategy attribute is used to customize the merge behavior
33     #[merge(strategy = merge::vec::append)]

54 A merge strategy is a function with the signature `fn merge<T>(left: &mut T,
55 right: T)` that merges `right` into `left`.  The `merge` crate provides
