Paperclip

Paperclip offers tooling for the OpenAPI specification. Once complete, it will provide:

• Code generation for efficient, type-safe, compile-time checked HTTP APIs (server, client and CLI) in Rust.
• Support for processing, validating and hosting OpenAPI spec.
• Customization for spec and code generation.

It's currently under active development and may not be ready for production use just yet.

You may be interested in:

• An overview.
• Examples.
• Features being worked on.
• API documentation.

Developing locally

• Make sure you have rustup installed. cd into this repository and run make prepare to setup your environment.
• Now run make to build and run the tests.

FAQ

Why is this generating raw Rust code instead of leveraging procedural macros for compile-time codegen?

I don't think proc macros are the right way to go for REST APIs. We need to be able to see the generated code somehow to identify names, fields, supported methods, etc. With proc macros, you sorta have to guess.

This doesn't mean you can't generate APIs in compile-time. The only difference is that you'll be using build scripts instead and include! the relevant code. That said, we're using proc-macros for other things.

The error thrown at compile-time doesn't look like it's very useful. Isn't there a better way to do this?

None that I can think of, sadly.

New ideas are here needed.
