Provide auto-instrumentation for OpenTelemetry standard

[Brian Greenhill]

First off, thanks so much for twirp!

The OpenTelemetry project has a repo containing autoinstrumenters for widely used packages (like net/http and others). This issue is to track work on creating auto-instrumentation for twirp. I'm interested to hear your thoughts. Is this something you would be open to for this project?

[Wade Matveyenko]

Thanks for your interest. We would be open to OpenTelemetry support, but it is not something we would actively work on. What changes would it need for hooks / interceptors?

[Brian Greenhill]

It shouldn't require any changes to twirp itself. It can be implemented as a middleware in combination with a server hook. There are some examples in public repos already. One example: https://github.com/chengjiagan/twirp-opentelemetry/
