NOTE This project is no longer actively maintained. If you're using redshift-rs, well, first: thank you :-) secondly, I'll happily accept patches via ~laumann/public-inbox or direct email to me.
History: Ever since I discovered the redshift utility, it was always one of the first tools I would install on a new OS install. Creating a reimplementation in Rust was about creating a project I would want to use while learning to write a non-trivial application in Rust.
In the spirit of Redshift this project is licensed under the GPLv3
