asgiref VS trust-dns

uvicorn is an ASGI server that is recommended for running FastAPI applications.

I can't seem to be able to edit on mobile. OP either meant this, or its variation, such as async_to_sync and sync_to_async.

Ofc this is a python example. I have no idea how it works in different languages.

FastAPI is a popular Python Web framework that developers use to create RESTful APIs. It is based on Pydantic and Python-type hints that assist in the serialization, deserialization, and validation of data. In this tutorial, we will use FastAPI to create a simple "Hello World" application. We test and run the application locally. FastAPI requires a ASGI server to run the application production such as Uvicorn.

Look at the intended semantics [1], and then read the implementation [2]. Can you figure out if the implementation is correct? Can you infer the possible limitations of the approach at glance? Can your async library actually handle being called with multiple event loops installed?

I have zero trust in this code and I have been bitten by fixes to this library that introduced deadlocks in my own code.

Using WebSockets in Django utilizes asynchronous Python and Django channels, making the process straightforward. Using Django channels, you can create an ASGI server, and then create a group where users can send text messages to all the other users in the group in real time. This way, you are not communicating with a particular user, but with a group, multiple users can be added.

If you're interested in the architecture itself I recommend you start by making yourself familiar with [ASGI specification](https://asgi.readthedocs.io/en/latest/) .

We switched to using strong typing derived from the asgiref for typing ASGI types, which makes Starlite the strongest type framework of its kind.

If you don't know what is Trust-DNS / Hickory DNS, this seems to be the repo: https://github.com/bluejekyll/trust-dns

IO is not a part of the async runtime contract (I don't know if this is good or bad), and Tokio & futures famously have different `Async{Read,Write}` traits. I once had to do this [0] to adapt between them.

This means that any crate that uses IO will be bound to a limited number of Runtimes. Everything being Tokio-only is pretty bad (though Tokio itself is great), but here we are...

I need a cert.pem and privkey.pem for https://github.com/bluejekyll/trust-dns but even using the extractor to get a cert.pem and privkey.pem from the acme.json file it seems invalid.

You might be interested in Trust DNS - "A Rust based DNS client, server, and Resolver, built to be safe and secure from the ground up."

It looks like you need to reach for a separate crate for that: https://github.com/bluejekyll/trust-dns/blob/7dcb7b983f5407d95d93b800af13caeee975aaa8/crates/async-std-resolver/src/lib.rs

You might be interested in new alternative to dig called dns https://github.com/bluejekyll/trust-dns/blob/main/util/src/dns.rs . I found out about it from https://twitter.com/benj_fry/status/1513269287229657091

I've found the Trust-DNS Resolver crate and it does the job! Now the binary seems to not use any dynamic library to look up the ip of a host.
