In #545 we replaced
Datum
's autogenerated bindings with an opaque pointer. Because bindgen was not generating the type, it could not know which traitsDatum
implements. This changed how containers ofDatum
were emitted. In particular containers ofDatum
no longer derivedDebug
,Copy
, orClone
. This also affected how unions containing these containers were emitted: bindgen only uses Rust unions if all members areCopy
, falling back to a struct of__BindgenUnionField<_>
fields otherwise.This change tells bindgen which traits our
Datum
implementation implements, fixing all of the above issues.
