withSpan/withSpanAsync helpers

[pauldraper]

I have to rewrite this in every project. Is there somewhere this can fit?

function withSpan<T>(span: Span, f: () => T): T {
  try {
    return context.with(setSpan(context.active(), span), f);
  } catch (e) {
    span.setStatus({
      code: SpanStatusCode.ERROR,
      message: (e && (e.stack || e.message)) || String(e),
    });
    throw e;
  } finally {
    span.end();
  }
}

async function withSpanAsync<T>(span: Span, f: () => Promise<T>): Promise<T> {
  try {
    return await context.with(setSpan(context.active(), span), f);
  } catch (e) {
    span.setStatus({
      code: SpanStatusCode.ERROR,
      message: (e && (e.stack || e.message)) || String(e),
    });
    throw e;
  } finally {
    span.end();
  }
}

maybe open-telemetry/opentelemetry-js-api#54 will fit your needs?

Well I would be happy to have this on api global level as stated here but seems it will not happen very soon. Unfortunately you are not the only one that see huge benefits in having such easy helpers, me too and I'm annoyed of using otel without such things. I was even thinking of simply creating a package called something like @opentelemetry-js-api-helpers etc. putting this anywhere and then simply combine all such helpers together. We don't need for such things any permission or wait then for any spec etc. It should be doable, unofficially but easier ;).

open-telemetry/opentelemetry-js-api#54 is under active development so i'm not sure what makes you think it isn't happening

Sounds like API is the right place. Thanks! Closing the issue here.
