Copy
and Clone
bindgen
will attempt to derive the Copy
and Clone
traits on a best-effort basis. Sometimes, it might not understand that although adding #[derive(Copy, Clone)]
to a translated type definition will compile, it still shouldn‘t do that for reasons it can’t know. In these cases, the nocopy
annotation can be used to prevent bindgen to autoderive the Copy
and Clone
traits for a type.
