Changing generated Typescript or C++ bindings templates

The central workings of a uniffi-bingen are its templates.

uniffi-bindgen-react-native templates are in the following directories:

• Typescript templates
• C++ templates

Templates are written for Rinja templating library.

The WASM crate is generated with quote, in the gen_rust module.

There is a small-ish runtime per target:

• typescript/src, with tests and polyfills. This is the TypeScript runtime, published to npm as @ubjs/core and shared by all targets.
• [’cpp/includes][cpp-runtime], the C++/JSI runtime for React Native, published as the uniffi-bindgen-react-native.podspec`.
• runtimes/napi, the N-API runtime for Node.js, published as @ubjs/node. Its Rust core is in runtimes/core.

This is intended to allow developers from outside the project to contribute more easily.

Making a change to the templates should be accompanied by an additional test, either in an existing test fixture, or a new one.

Running the tests can be done with:

cargo test

An individual fixture can be tested:

cargo test -p uniffi-fixture-$fixtureName
