**WARNING**: This crate is no longer actively maintained.
This package is a rough rust port of the
[`cccolutils` python package][cccolutils.py].
[cccolutils.py]: https://pagure.io/cccolutils
The C part is inspired by the CPython extension from this python package, with
some adaptations and fixes for all the memory leaks I could find (using valgrind
with a small C test program, and the leak sanitizer from nightly rust for the
rust code).
The available API is currently limited to the following three functions:
- `fn get_username_for_realm(realm: String) -> Result<Option<String>, String>`:
determine the username of the authenticated user for a given realm
- `fn has_credentials() -> bool`: determine if there are any active
authentication tickets for any realm
- `fn has_credentials_for_realm(realm: String) -> Result<bool, String>`:
determine if there is an authenticated user for the given realm
The style of the C code is enforced with the uncrustify configuration in this
directory.
