Wow Rust so great at optimizing stuff

Basically this

#[derive(Clone, Copy, Debug, Eq, PartialEq)]
enum Orientation {
    North,
    East,
 South,

Terrain

The generation of terrain is done using Add*Layer classes, composed together. The following table comes from an old forge version where they're mapped as GenLayer*.

Layers return an int/i32 for every (x, z) that have different possible interpretations depending on the layer. For some, it's completely abstract, others return biome ids, others return other values. This is the second column.

Constructor parameters are the effective parameters that are used by the layer. base is the "base seed", used in the PRNG.

ADT "constructor"
Very elementary type-safe function-based "match"

spotifyPause.sh

This short script allows the Play/Pause keyboard key to be also used to start Spotify (or any player of your choice with a bit of tweaking). I'm using Cinnamon's settings to reassign keys, but other distros may also have this feature

Setup

Download/copy the script somewhere on your system
chmod +x ./spotifyPause.sh to make it runnable
Add the new keybinding [Cinnamon only]
Open cinnamon-settings keyboard (you can search for "Keyboard" in the start menu search if you don't like terminals)
