#[non_exhaustive]pub enum FilterChange {
Different,
LessStrict,
MoreStrict,
}
Expand description
Describes changes in a filter in more detail and allows objects using the filter to optimize refiltering items.
If you are writing an implementation and are not sure which
value to pass, Different
is always a correct
choice.
Variants (Non-exhaustive)§
This enum is marked as 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.
Different
The filter change cannot be described with any of the other enumeration values.
LessStrict
The filter is less strict than
it was before: All items that it used to return true
for
still return true
, others now may, too.
MoreStrict
