How to get attribute from span

[HolyMiss]

The current Span class only provides the SetAttribute method. What should I do if I want to get the attributes in span in the Propagater I implemented?

otel-cpp doesn't provide Readable Span interface. To optimize performance, the SDK implementation avoids keeping an intermediate copy of the attributes passed via Span::SetAttribute(), opting instead to serialize them directly to the exporter format. This approach complicates the provision of a Readable Span. Previous discussions, and somewhat non-trivial solution on this can be found in issues #2108 and #1475.

@HolyMiss - Do you have further questions, or the issue can be closed based on above reasoning ?
