Enum Change 

#[non_exhaustive]
pub enum Change<'a> {
    Added(&'a Entry),
    Removed(&'a Entry),
    Modified {
        before: &'a Entry,
        after: &'a Entry,
    },
}

A structural field change; unchanged values allocate no copy.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Added(&'a Entry)

Removed(&'a Entry)
