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

Ah yeah, if I switch to stable from nightly it seems to have a bit of trouble.

Also turning on expand makes it get grumpy about the diesel items in the crate, so maybe I should just do it by hand. My API changes made it nice enough that it's just a few lines to copy-paste.

Curious about what the error was. We should try to fix that
