4//! `p5-sys` crate(library) is bindings to [p5.js](https://p5js.org/) for Rust/Wasm.
5//! 
6//! *** Nightly rustc is required ***
7//! 
8//! Currently,almost all global function works. The instance methods and properties don't work.
9//! For example, `vector.add()` will not work. You are advised to use rust types for such tasks. 
10//! Also functions that take arrays and modify them will not work. 
11//! 
12//! The documentation is taken from p5.js reference and are not ported to rust yet.
13//! 
14//! # Example
15//! ```no_run
16//! use p5::*;
17//! 
18//! pub struct State {
19//!     x: f64,
20//! }
21//! 
22//! #[wasm_bindgen]
23//! pub fn setup() -> State {
24//!     createCanvas(400., 400., RENDERER::Webgl);
25//!     background(123., 234., 124.);
26//!     return State {
27//!         x: 10.,
28//!     }
29//! }
30//! 
31//! #[wasm_bindgen]
32//! pub fn draw(state: &mut State) {
33//!     state.x += 1;
34//!     rect(state.x, 40., 100., 120.);
35//! }
36//! ```
37//! 
38//! We don't have mutable global variable in Rust, so we have to use state.
39//! setup creates the state. draw and other event handlers recieve
40//! a mutable reference to it, means that they can change it.
