Async Interceptor support

[heartforit]

Hi,

I was wondering after hours of research how to implement a simple async interceptor method without tons of boilerplate code. I scanned the examples folder without success. In my opinion, it should be easy for the developer to write and handle async code with rust. My ugly solution for now is

fn my_interceptor_sync(request: Request<()>) -> Result<Request<()>, Status> {
    tokio::task::block_in_place(|| {
        tokio::runtime::Runtime::new()
            .unwrap()
            .block_on(my_async_interceptor(request))
    })
}

But this code is pretty bad. How can I improve it? I could not find anything useful.

Best

I tried: https://crates.io/crates/tonic-async-interceptor But it its apart from the current main implementation, but it seems to work.

Works with this matching version combination (took me hours to figure that out)

[dependencies]
tonic = "0.11"
prost = "0.12"
tokio = { version = "1.0", features = ["macros", "rt-multi-thread"] }
tower = "0.4.13"
futures-util = "0.3.30"
tonic-async-interceptor = "0.11.1"

[build-dependencies]
tonic-build = "0.11"
