I have recently pushed up two different crates. The first, marid, is a library for managing parallel, long-running threads within a process. Notably, this crate exposes an easy interface for responding to signals as a shutdown mechanism. I have just published a small blog post detailing more about it.

The second crate is a Rust testing DSL in the TDD/BDD style. It is currently on v0.1.0, but is definitely usable for many different cases. Inspired by such matcher libraries as rspec and ginkgo , my favorite feature is the support for async-style expectations with the eventually and consistently assertions. For this crate I am really looking for information on what types of other matchers people would find useful, so please take a look at the current docs and let me know if there is anything you would want that is missing.
