That's a wicked cool tool! Thank you for sharing.

I do think there is room for both tools though. One of the cooler things I did with `xsv` was implement a very basic form of indexing. It's just a sequence of byte offsets where records start in some CSV data. Once you have that, you can do things like process the data in parallel or slice records in CSV instantly regardless of where those records occur.

It helps when the CSV parser has support for this: http://burntsushi.net/rustdoc/csv/struct.Reader.html#method....
