My codebase is split into multiple crates. I have one crate that uses safer-ffi and has #[derive_ReprC]s on various data types, guarded by a c_api feature. I have another crate that depends on the first one, and also uses safer-ffi to expose some functions to C.

The second crate is putting all types and functions from the first crate used in #[ffi_export] into the header file as well as the second crates #[ffi_export]s, even though I would rather have the header file simply include the header from the first crate. I'm concerned that if I were to #include both files, I would have duplicate function declarations.

This isn't a minimally reproducible example at all, but in case its helpful, here is the second crate:
https://github.com/0xTELEPORTAL/tp-platform/blob/29c62451672d3a353f98cddef7c7c951b356973e/demos/unity_states/rust/src/lib.rs

here is the generated header, which includes many functions not defined in the crates `lib.rs`:

So, multiple function declarations of the same item may be fine, but the type definitions will indeed be problematic.

It's actually complex / difficult for safer-ffi, alone, to make that split, since it doesn't know of crate boundaries.

The way I'd do it, then, following the more "modern" approach of header generation (that of having the lib export a header-generating function, so as to then have either a unit-test or an example binary call that function):

  1. Have the first library (in your case, ::tp_client?) export a helper function for this, one taking a &mut HashSetDefiner:

    • EDIT: hmm, generate_with_definer consumes ownership of its impl Definer arg (definitely an oversight!) so this suggestion will need some fixes from my side to be usable:
    // #[cfg…] /* feel free to cfg-gate etc. */
pub fn generate_headers_with_definer(
    definer: &mut ::safer_ffi::headers::HashSetDefiner,
) -> ::std::io::Result<()>
{
    ::safer_ffi::headers::builder()
        .generate_with_definer(definer)?
}

    The key idea is that an impl Definer, such as HashSetDefiner, has to remember the items they've already generated / emitted, precisely to avoid duplicated definitions within a header generation pass.

    So, by using this more advanced API, the resulting Definer is not lost, but left under the caller's power/reach. _Such resulting Definer thus, by definition, will prevent any definitions of these already-defined items!

    The caller will then be able to swap the out field of that definer when using it to generate a second header (that of the dependent crate (e.g., ::unity_states).

  2. In the header generation function of the dependent crate (e.g., ::unity_states):

    1. Hand-roll the HashSetDefiner's construction:

      let ref mut dummy = ::std::io::sink();
let mut definer = HashSetDefiner {
    defines_set: <_>::default(),
    out: dummy,
};

    2. Call into the previously defined function:

      ::tp_client::generate_headers_with_definer(&mut definer).unwrap();

    3. Tweak the resulting HashSetDefiner so that now it generates the header where you want it to:

      let ref mut real_out = ::std::fs::File::options()
    .write(true)
    .truncate(true)
    .create(true)
    .open("generated.h")?;
definer.out = real_out;

    4. Generate your new headers:

      ::safer_ffi::headers::builder().generate_with_definer(definer)?;

This last step should have done exactly what you wanted (but for #include-ing the previous header, which for the moment you'll have to manually tweak yourself): generate a header for ::unity_states without reëmitting any of the items exported by ::tp_client.

I'll admit it's quite rough at the moment; it could be envisioned to expose a few helper macros to make this smoother:

  1. Slap a ::safer_ffi::generate_headers!(to = "filename.h"); on ::tp_client's src/lib.rs;
  2. Slap a ::safer_ffi::generate_headers!(skip = ::tp_client, import = "filename.h", to = "other_filename.h"); on ::unity_states's src/lib.rs.

OK, sorry for the slow response. I ended up not doing this because it was complicated, but now that is biting me and I'm forced to deal with my past decisions XD. So I'm looking at actually doing this properly now.

It looks like I'll need to make a simple PR to have generate_with_definer consume the definer by &mut instead of ownership.

Then, for every crate that I want to create headers for, I have to provide a "generate the headers only for this crate" function, which accepts a &mut impl Definer.

To implement that function, I would then call the corresponding functions from all dependencies first using a definer with a Writer that does nothing (think /dev/null). That will collect all the types from the dependent crates. Then I put back in the actual writer and do the final write, which should contain only the current crate's types.

Whew that is a lot of stuff, but conceptually it is simple.

In the time since I originally posted the question, did you get any ideas on how to solve this is in a more robust way? If we had a registry of types in the current crate somehow, this would be a non-issue I assume. Is there no way to accomplish that with rust?

Maybe we could add a unique string for the crate (either a hash or the crate name + version directly) to each type that implements ReprC? The attribute macros would read this information from CARGO_PKG_VERSION and CARGO_PKG_NAME` and that could go into the generated trait implementations.

Perhaps an approach could be like prost for protobufs where each type is associated with a package, and a graph of all the type information is known before generating multiple files at once.

But in here they could be associated with a header file that is relative to the path defined at the crate-level which can overwritten at build time if necessary. So not necessarily at the source file level like mentioned above. That way if I'm using a monorepo-like workspace, a type named like Error in my_corp_util crate could be known to be found in the my/corp/util.h file for example, while something else like LocalizedText could be found in my/corp/strings.h -- both from same crate. For example code purposes, usually each crate would provide a type specification set rather than a builder that can directly write only a single file. That gives the flexibility of generating multiple header files at once, especially if project is only producing a single static library for example.

If the type graph is also provided as the result of header generation, the end user could also make use of it for further custom code generation like making a bridging header for xcode builds.

The safer_ffi types of course would need to be in a well known, possibly configurable location, like safer_ffi/safer_ffi.h that also be added to the user's include search path. Include file path and crate name would also be very helpful with any custom naming plugins as well.
