if you target c, it does this automatically for every substitution it finda

If I want to write destructors for all of these I need a macro, right?

yeah you can’t pass drop/dtor types by value the abi doesn’t work

Oh I mean like, explicit free(T) functions

// My solution: #[repr(C)] pub struct RawVec<T> { len: usize, ptr: *mut T, } macro_rules! free_vec { ($($name:ident : $T:ty,)+) => {$( #[no_mangle] pub extern "C" fn $name(vec: $T) { drop(vec.into_vec()) } )*} }

And then manually do like free_vec! { cs_free_comics: RawVec<ComicId>, } for every type I care about

yeah that's basically what you need to do but doing it with macros is a pain in the ass since you need to use the unstable rustc expland flags for cbindgen to be able to see the code
