uniffi-js

This directory contains C++ helper code for the UniFFI Rust library (https://github.com/mozilla/uniffi-rs/).

UniFFIPointer.* and UniFFIPointerType.* implement the UniFFIPointer WebIDL class
UniFFI*Scaffolding.cpp implements the UniFFIScaffolding WebIDL class.
- UniFFIGeneratedScaffolding.cpp contains the generated code for all non-testing UDL files.
- UniFFIFixtureScaffolding.cpp contains generated code for test fixture UDL files. It's only compiled if --enable-uniffi-fixtures is set.
- UniFFIScaffolding.cpp is a facade that wraps UniFFIFixtureScaffolding, and UniFFIGeneratedScaffolding if enabled, to implement the interface.
ScaffoldingConverter.h, ScaffoldingCall.h contain generic code to make the scaffolding calls. In general, we try to keep the logic of the calls in these files and limit the generated code to routing call IDs to template classes defined here.
OwnedRustBuffer.* implements a C++ class to help manager ownership of a RustBuffer.
UniFFIRust.h contains definitions for the C functions that UniFFI exports.
