I removed writing the resource for every span, as the field was removed from SpanData.

@kcking-openai thanks for the PR. Regarding resource, while it was removed from SpanData, SpanExporter::set_resource() method was introduced for one time setting of resource in Exporter. Default implementation was added for it in the SpanExporter trait so that custom exporters don't break. You may want to implement the DatadogExporter ::set_resource() method instead of removing resource from the code.

Also, you have to sign the easyCLA before the PR can be approved.

Thank you @lalitb, I have completed the CLA and pushed a fix for the lint. If you would like an alternative solution to the too_many_arguments lint I could wrap them in a struct, but I wasn't sure it was worth the effort at this point.

[kcking-openai]

And I just pushed a fix for some lints that had broken in a couple unrelated directories.

[lalitb]

Thanks @kcking-openai. This looks good. Will publish a release shortly.
