I’m using Rust Polars, and want to convert from a number stored as a string to a binary representation of the value as a binary column. This is so I can do some comparisons on IPv6 numbers, which are too big to store in the Polars Decimal type.

I’m working with huge datasets and considering using Polars.
My goal is to write data in NDJSON format to S3. And it should be partitioned.
My data is usually much bigger than my SSD.

I’m trying to create a list series of type utf8 in rust.

I’m having a hard time converting a Series of strings into an array to iterate in a for loop.
