Announcing cccolutils-rs

It's already been available for some time, but I still want to announce a
small pet project I've been working on - a Rust port of the cccolutils Python package. It consists of some small helper
functions written in C, and correspondig FFI bindings for Rust.

I chose to write (and adapt) some glue code in C instead of using FFI directly, because the original Python package does the same thing - and there aren't any usable and complete FFI bindings for the MIT Kerberos 5 library available.

cccolutils-rs (cccolutils on https://crates.io) provides some very basic functions for querying the Kerberos credentials cache (e.g. checking whether there's an authenticated user for a given realm). The current state of the code can be viewed on GitHub.

I'm also working on complete rust FFI bindings for the krb5 library, which would make it possible to drop the C glue code in the future, once I can rely on proper FFI bindings.
