I see there are functions for applying various compression algorithms to files, however I'm wondering if you could expose functions to allow those same compression algorithms to be used on in-memory data, such as a Str for example, or even just a Ptr to a location in memory with a specified size?

You could use the File interface for that. It also supports in-memory.

Thanks buddy, yes I know I could use the File interface, however I'm not sure how much overhead there would be when converting data to and from a File, i.e. would there be any significant performance penalties with using the File interface in this way?
