Polars Dataframe, ndarray and charming dataframe

[jiawen wang]

Hi,
What are the differences between rust polars dataframe/ndarray and charming dataframe ? The polars and charming dataframe are both created with df! macro. Can I use polars/ndarray instead of charming dataframe ? If not, how to convert them to charming dataframe ?
