Compilation Error for README Example in 3 Separate Crates

[Neightro]

I'm a newcomer to this crate. I noticed that the documentation mentioned that the interface and implementation generally reside in separate crates, so I was trying to get the example working in that fashion. I commented out the single-crate version of load_root_module_in_directory and uncommented the 3-crate version. However, cargo build -p implementation then results in:

error[E0117]: only traits defined in the current crate can be implemented for types defined outside of the crate
   --> implementation/src/lib.rs:112:1
    |
112 | impl<T> Appender for RVec<T> {
    | ^^^^^^^^^^^^^^^^^^^^^-------
    | |                    |
    | |                    `RVec` is not defined in the current crate
    | impl doesn't use only types from inside the current crate
    |
    = note: define and implement a trait or new type instead

What would be the recommended solution? I don't have enough knowledge of abi_stable to answer that myself.

My example repository, if helpful: https://github.com/Neightro/abi_stable_readme_example

Yes, the README example is wrong, apparently I edited it without trying it out in actually separate crates.

I'll fix the code in the README, and make it so that there are crates in the examples directory to run.

Perfect! Thanks for the quick response.
