# System preferences backend
## defaults-rs
In order to automate the process for setting up System Preferences, instead of relying on the `defaults` command, cutler uses
the [defaults-rs](https://github.com/machlit/defaults-rs) crate.
It communicates with the preferences daemon through the CoreFoundation API bindings in Rust. This is primarily known as the `cfprefsd` process inside macOS, which is used for setting, storing and caching preference and/or default key-value pairs.
You can view the source of the backend through the given links below. Consider contributing to make it even better for everyone!
