error[E0277]: the trait bound Self: std::marker::Sized is not satisfied

I tried to build it running cargo build at rustc 1.16.0 (30cf806ef 2017-03-10), and got this:

Again, not a bug in this crate, and not one I can help you with.

This looks like it is probably due to you having a different version than that version of rayon requires, or it just doesn't build on Windows for some reason. I have no idea.
