Our CI just bumped the Rust toolchain to 1.46 and we started seeing FFI errors. I would expect the safe FFI annotations to be declared by Rutie, so all projects that use this library don't need to change their code, but I don't know if that's possible.
These are the errors:
15 | class!(BundleRemaps);
| ^^^^^^^^^^^^^^^^^^^^^
= note: this error originates in a macro (in Nightly builds, run with -Z macro-backtrace for more info)
error: `extern` fn uses type `BundleRemaps`, which is not FFI-safe
--> mesh-ruby/src/lib.rs:19:5
|
19 | BundleRemaps,
| ^^^^^^^^^^^^ not FFI-safe
|
= help: consider adding a `#[repr(C)]` or `#[repr(transparent)]` attribute to this struct
= note: this struct has unspecified layout
note: the type is defined here
