# `async-google-apis` This software generates asynchronous API stubs for Google APIs (and most likely any other API described by a Discovery document). It uses [`yup-oauth2`](https://github.com/dermesser/yup-oauth2) for the authorization logic. This project is still experimental. While for many complex APIs (Cloud Storage, Drive v3, Sheets v4) usable APIs including types and documentation are generated successfully, this doesn't mean that it will work on any other current or future Google API. ## Parts * `manual_demo` is just a demo crate with some code for developers (well, me) to experiment if the generated APIs work, and also to work manually with the Google APIs to gain insights on which code to generate. * `generate` contains a Python program fetching current Google Discovery documents (https://www.googleapis.com/discovery/v1/apis, see [documentation](https://developers.google.com/discovery/v1/reference)) and generating Rust code in the `generate/gen` directory. This is done very non-fancily using a few mustache templates and the `chevron` package. The script only takes two parameters, which you can discover using `--help`. In short, to generate an API stub for the API with ID `storage:v1` (Google Cloud Storage v1), run ```shell $ pipenv run ./generate.py --only_apis=storage:v1 ``` (install `pipenv` using `pip install --user pipenv` before, if you don't have it yet). See more details in that directory. * Consult `drive_example` for a simple but useful example of using the generated code. As you can see, it is reasonably easy! Use `cargo doc` to generate the documentation for generated code, as the API comments is translated into Rust doc comments. * `async-google-apis-common` contains shared code, for example the HTTP logic, used by the generated code, as well as some types (like errors) and as well as all imports. Include this crate in your dependencies when you are using the generated code in your project. ## To Do * No resumable uploads -- even big files need to be held in memory.
