Is your feature request related to a problem? Please describe. I'm exporting data from APIs that provide e.g. OpenAPI Specs, and the data is then transformed and used elsewhere. The downstream usage is more database-like, where tools like ibis come really handy. That however doesn't work with e.g. the suggested Pydandtic v2 generated models. What would work, instead is using a model defined by Pandera's DataFrameModel, which then can be validated, and transformed between very different dataframe types. Describe the solution you'd like Being able to select --output-model-type to be something like "pandera.DataFrameModel", and it would generate the data model + fields based on the OpenAPI spec. Describe alternatives you've considered Manually translating the generated Pydantic schema into Panderas schema, or adding conversions for each generated model along these lines. Additional context None at the moment.
