pub fn marked_attr_names(marker: Key<bool>) -> HashSet<&'static str>Expand description
Returns the set of all declared attribute key names that carry
the given bool meta marker (set to true) in the attrs
inventory linked into the current binary.
Generic category-membership enumeration. Used by consumers that maintain explicit hard-coded category sets (for auditability) to validate the set matches the declaration-driven vocabulary; drift between the two is a bug.
