Multiple-instrument callbacks for observables #112

Closed mortenpi closed 3 months ago

mortenpi commented 3 months ago

This is a bit similar to https://github.com/oolong-dev/OpenTelemetry.jl/issues/85, but distinct in that the idea is to set multiple different instruments in one callback call (potentially different types of instruments, so attributes are not a suitable workaround either I think).

The spec has a suggestion for an API: https://opentelemetry.io/docs/specs/otel/metrics/api/#multiple-instrument-callbacks

Is there some way to achieve this right now? If not (which I think is the case), is this something that should be supported? Any thoughts on the API?

Should be easy to support.

（I had thought about this while reading data from NVSwitch;）
