--------------------------------
Labels: async-util (was: )
> [C++] Investigate moving away from std::function in AsyncGenerator
> ------------------------------------------------------------------
>
> Key: ARROW-12177
> URL: https://issues.apache.org/jira/browse/ARROW-12177
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++
> Reporter: Weston Pace
> Assignee: Weston Pace
> Priority: Major
> Labels: async-util
>
> Most of async_generator.h uses std::function to store the operator functions.
> Primarily this was to simplify the implementation. However, now that it is
> being used more it ends up being somewhat wordy because lambda cannot be
> implicitly assigned to std::function. This has gotten to the point where we
> have created templated overloads that wrap the lambdas in functions.
> It may be time to take a second look at this decision and converting over to
> templated callable types.
