pub unsafe static kMDQueryUpdateRemovedItems: Option<&'static CFString>Available on crate feature
MDQuery only.Expand description
The name of the key in a query notification’s info dictionary which identifies the list of removed results. A result can be removed if it no longer matches the query. The list only contains result objects which have previously been created, and does not indicate results which have been removed for which result objects have not been created. [[This is for performance reasons, to avoid creating temporary result objects just to represent the deletion of the result, but this semantic may change.]]
