pub fn copy_marked_flattrs(dst: &mut Flattrs, src: &Flattrs, marker: Key<bool>)Expand description
Copy every entry from src to dst whose declared attribute
key carries the bool meta marker marker with value true.
Overwrite semantics (see Flattrs::set_serialized). Entries
whose declared key lacks the marker — or whose key_hash does
not resolve to a declared key in the current binary’s
inventory — are silently skipped.
Generic category-filter Flattrs → Flattrs copy. The companion
of stamp_marked_attrs_into_flattrs for callers that already
have a source Flattrs in hand (forwarding, hoisting) rather
than an in-memory Attrs.
