Show HN: Generate HTTP and Jsonrpc from IDL

I've extended the functionality of (OMG DDS)IDL and written a code generator. It can generate C/C++/Rust/Rust HTTP/Rust JsonRPC/OpenAPI/OpenRPC code from IDL.

Of course, the Rust HTTP/Rust JsonRPC/OpenAPI/OpenRPC generation is currently more mature.

I previously used utoipa to generate OpenAPI from code, but I quickly grew tired of the endless boilerplate code. So I made this!!!

Simply put, you use IDL to describe an HTTP service, and I'll generate an interface, a Service. If you implement an interface for a given interface, I can generate routes for you. It works like this...

```rust

use xidlc_examples::hello_world::HelloWorld;

use xidlc_examples::hello_world::HelloWorldSayHelloRequest;

use xidlc_examples::hello_world::HelloWorldServer;

struct HelloWorldImpl;

#[async_trait::async_trait]

impl HelloWorld for HelloWorldImpl {

    async fn sayHello(

        &self,

        req:

xidl_rust_axum::Request<HelloWorldSayHelloRequest>,

    ) -> Result<(), xidl_rust_axum::Error> {

        let HelloWorldSayHelloRequest { name } = req.data;

        println!("Hello, {}!", name);

        Ok(())
    }

}

#[tokio::main]

async fn main() -> Result<(), Box<dyn std::error::Error>> {

    let addr = "127.0.0.1:3000";

    println!("axum hello_world server listening on {addr}");


    xidl_rust_axum::Server::builder()
        .with_service(HelloWorldServer::new(HelloWorldImpl))
        .serve(addr)
        .await?;

    Ok(())

} ```

Currently, support for streaming (HTTP/JsonRPC) is still quite basic. It's defined at https://github.com/xidl/xidl/tree/master/docs/rfc

Besides that, I've used HTTP/OpenAPI in my project, and I think it currently meets my overall needs.

Furthermore, xidlc provides simple interfaces for extension. I find xidlc's design truly fascinating.

I've added some snapshot tests to avoid regression issues.

I used Google Translate to translate this post, so I'm not sure if it conforms to English grammar. I sincerely hope to receive any feedback, thank you.
