''← [[SDK 6.3]] · Rust''

Rust cubeapps are built to WebAssembly and use the same engine ABI as the [[SDK 6.3/C++/Native API|C++ native API]]. The Development Kit ships the '''<code>wowcube_sdk</code>''' crate (v0.1.0) together with buildable Rust example projects (''Basics 1–3'', with assets). Projects are created and built with the [https://marketplace.visualstudio.com/items?itemName=cubios-inc.WOWCubeSDK WOWCube SDK extension for VS Code].

== Crate layout ==

[package]
name = "wowcube_sdk"
version = "0.1.0"
edition = "2021"

[dependencies]
cty = "0.2.2"

* <code>wowcube_sdk::application</code> — the <code>Application</code> trait, <code>ApplicationContext</code>, timers, animation helper (<code>Anim</code>), error type <code>AppErr</code>, and the entry helpers <code>application_init()</code> / <code>application_run()</code>.
* <code>wowcube_sdk::cubios</code> — FFI bindings to the engine ABI and the typed submodules <code>comm</code>, <code>gfx</code>, <code>topology</code>.

== Application trait ==

A cubeapp implements the <code>Application</code> trait; all callbacks have default no-op implementations, so you override only what you need:

pub trait Application {
fn app_context_mut(&mut self) -> &mut ApplicationContext;

fn on_init(&mut self) -> Result<(), AppErr> { Ok(()) }
fn on_tick(&mut self) -> Result<(), AppErr> { Ok(()) }
fn on_render(&self) -> Result<(), AppErr> { Ok(()) }
fn on_timer(&mut self, _timer_id: u8) -> Result<(), AppErr> { Ok(()) }

fn set_timer(&mut self, id: u8, delay: u32, suspended: bool) -> bool { … }
}

Errors are reported through the <code>AppErr</code> enum (<code>AssetNotFound</code>, <code>InvalidModule</code>, <code>InvalidTwist</code>, <code>SceneNotFound</code>, …).

== Entry points ==

The module exports two <code>extern "C"</code> functions which the runtime calls (from the shipped ''HelloWOWCube'' example):

#![no_main]
mod cubeapp;
use wowcube_sdk;

static mut APPLICATION: Option<cubeapp::HelloWOWCube> = None;

#[no_mangle]
pub extern "C" fn on_init(cid: u32) {
let mut application = cubeapp::HelloWOWCube::new();
wowcube_sdk::application::application_init(&mut application, cid);
unsafe { APPLICATION = Some(application); }
}

#[no_mangle]
pub extern "C" fn run() {
let application = unsafe { APPLICATION.as_mut().unwrap() };
wowcube_sdk::application::application_run(application);
}

<code>cid</code> is the index of the module (0–7) the instance runs on — the same value as <code>cubeN</code> in C++ and <code>SELF_ID</code> in PAWN; it is also available as <code>cubios::CUBE_N</code>.

== FFI types ==

<code>wowcube_sdk::cubios</code> mirrors the [[SDK 6.3/C++/Native API#Types and data structures|native types]] with Rust naming:

pub struct TopologyFaceletInfo { pub module: i32, pub screen: i32, pub connected: i32 }
pub struct TopologyPlace { pub face: i32, pub position: i32 }
pub struct TopologyTwistInfo { pub screen: i32, pub count: i32, pub direction: i32 }
pub struct LbInfo { pub board_count: i32, pub self_position: i32,
pub self_achivement: i32, pub whole_user_list_count: i32 }
pub struct GfxParticle { ttl, vx, vy, ax, ay, explosion, velocity,
duration, frequency, max, loop, time }

Enumerations: <code>TopologyNeighbour</code> (None/Left/Diagonal/Top/Right/Bottom), <code>TopologyOrientation</code> (Menu/Gravity/Splash), <code>TopologyLocation</code> (Up/Down/Front/Back/Left/Right), <code>TextAlign</code> (9 values), <code>LogLevel</code>, <code>UartId</code>; constant <code>NET_BROADCAST = 0xFF</code>; type aliases <code>SoundId</code>, <code>SpriteId</code>.

For the semantics of the underlying engine functions (graphics, sound, topology, sensors, leaderboard) see the [[SDK 6.3/C++/Native API|native API reference]] — names and behavior match one-to-one.

== Examples ==

The Development Kit ships three buildable Rust projects under <code>examples/…/rust/Basics</code>, each with a <code>project/src/main.rs</code>, <code>cubeapp.rs</code>, an <code>assets/</code> folder and a <code>wowcubeapp-build.json</code> build manifest.
