pub fn annotation_alter_family(kind: &Kind) -> Result<Option<AnnotationFamily>>Expand description
Returns the annotation family when kind is a SET/UNSET whose keys all
belong to one family — the alters that only rewrite table metadata and skip
region dispatch. A mixed batch is an error; never interpret it as “not an
annotation alter”, or the batch falls through to a path that reports a
misleading error (or dispatches to regions).
