## 📔 Objective

These crates had some missing features, which caused compilation errors
when trying to run the tests from VSCode. The reason that CI kept
building was that rust unifies all the workspace features, so as long as
one crate has them enabled it's fine. On the other hand, when running a
test from VSCode, it will only have that crates features in mind.

Note that the uniffi feature of core requires internal because of these
two types:
