I added rayon and mime to on-deck evaluations. rayon is about ready for 1.0, and very popular. mime also gets around a lot and libs team has expressed interest. I demoted env_logger to out-of-band evaluations, as I don’t see the libs team revisiting logging any time soon. I’m still hopeful to get some such evaluations going soon.
The csv crate is also about ready for 1.0, and would be worthy of review. As a @burntsushi crate it’s going to be super high quality. I’m a little iffy about whether it is within the present mandate of this project, though certainly csv is a common format, and is sometimes supported by standard libraries.
