# deckster
> A custom Loupedeck driver and declarative backend written in Rust

## To do
- Make the `playerctl` handler independent of… playerctl. Use the [`mpris` crate](https://lib.rs/crates/mpris) directly instead.
- Implement scrolling
- Move loupedeck_serial and pa_volume_interface out of this repository.
- Publish libraries to crates.io
- Move handlers to their own repositories

## Contributing

### Terminology
- `handler runner`: Node that is running handlers.
- `handler host`: A `handler runner` that is not the `coordinator`.
- `coordinator`: Node to which the Loupedeck device is physically connected. Can be a `handler runner`.


### The different types of `unwrap`
- `expect("<reason>")`: The author thinks that unwrapping will never fail because of `<reason>`. 
- `unwrap()`: The author assumes that unwrapping will never fail ~~but explaining why is either obvious or too complicated~~ and it’s obvious why.
- `unwrap_todo()`: The author has not yet thought about how to handle this value being `None` or `Err`.
  They will replace this unwrapping with `expect("<reason>")`, `unwrap()`, or proper error handling later.
