Overview

Keeps user’s DSL configuration for a particular io-pipe step. Implements the interface for the actual I/O code and is DSL code happening in the normalizer. The actual I/O code expects In and Out objects to generate the two io-pipes.

If a user needs to inject their own private iop step they can create this data structure with desired values here. This is also the reason why a lot of options computation such as :with_outer_ctx happens here and not in the IO code.
