### simple.rs example using Color::rgb

Source: https://docs.rs/orbclient/latest/orbclient/color/struct.Color.html?search=u32+-%3E+bool

This example from examples/simple.rs gets the display size and creates a window, using Color::rgb to set the background.

```rust
fn main() {
    let (width, height) = orbclient::get_display_size().unwrap();
```

### Example: Drawing with GraphicsPath::move_to in examples/simple.rs

Source: https://docs.rs/orbclient/latest/orbclient/graphicspath/struct.GraphicsPath.html?search=std%3A%3Avec

This example from `examples/simple.rs` demonstrates `move_to` within a full window drawing program. It creates a transparent window, draws gradients, arcs, circles, lines, and uses `move_to` to start a cloud path and a balloon path before stroking them. The example also includes an event loop that prints pixel colors on mouse events.

```rust
fn main() {
    let (width, height) = orbclient::get_display_size().unwrap();

    let mut window = Window::new_flags(
        (width as i32) / 4,
        (height as i32) / 4,
        width / 2,
        height / 2,
        "TITLE",
        &[WindowFlag::Transparent],
    )
    .unwrap();

    let (win_w, win_h) = (width / 2, height / 2);

    let start = Instant::now();
    // top left -> bottom right
    window.linear_gradient(
        0,
        0,
        win_w / 3,
        win_h,

        (win_w / 3) as i32,
        (win_h / 2) as i32,
        Color::rgb(128, 128, 128),
        Color::rgb(255, 255, 255),
    );
    // horizontal gradient
    window.linear_gradient(
        (win_w / 3) as i32,

Partial example from examples/simple.rs (line 143) showing the start of a main function; the rest is not shown on this page.

```rust
fn main() {

### get example

Source: https://docs.rs/orbclient/latest/orbclient/event/struct.Event.html?search=Option%3CT%3E%2C+%28T+-%3E+U%29+-%3E+Option%3CU%3E

Demonstrates the `get` method on a slice. It returns a reference to an element or subslice depending on the index type, or `None` if out of bounds. The example shows both element and range indexing.

```rust
let v = [10, 40, 30];
assert_eq!(Some(&40), v.get(1));
assert_eq!(Some(&[10, 40][..]), v.get(0..2));
assert_eq!(None, v.get(3));
assert_eq!(None, v.get(0..4));
```

Example for the first method, returning the first element or None if empty.

```rust
let v = [10, 40, 30];
assert_eq!(Some(&10), v.first());

let w: &[i32] = &[];
assert_eq!(None, w.first());
```

### Renderer drawing example with gradients, paths, shapes, and modes

Source: https://docs.rs/orbclient/latest/orbclient/renderer/trait.Renderer.html

Example from the repository demonstrating various Renderer drawing methods: linear_gradient, arc, circle, wu_circle, line, wu_line, GraphicsPath with bezier_curve_to and quadratic_curve_to, draw_path_stroke, char, getpixel, rect with Mode::Blend and Mode::Overwrite, box_blur, box_shadow, and sync. Includes a PartialEq test for Color and a non-existent pixel getpixel that returns Color(0,0,0,0) without panicking. The code is incomplete at the start (missing window creation) and ends with an unfinished event loop.

```rust
    width / 2,
    height / 2,
    "TITLE",
    &[WindowFlag::Transparent],

### Drawing example using orbclient window functions

Source: https://docs.rs/orbclient/latest/orbclient/color/struct.Color.html?search=u32+-%3E+bool

A comprehensive example demonstrating drawing with orbclient. It draws arcs, circles, lines, paths, text, rectangles, and applies effects like blur and shadow. It also shows setting drawing modes (Blend/Overwrite), getting pixel colors, checking Color equality, and handling events. Note: Overwrite mode and alpha hole may be Orbital-specific.

```rust
window.arc(100, 100, -25, 1 << 4 | 1 << 6, Color::rgb(255, 0, 255));
window.arc(100, 100, -25, 1 << 5 | 1 << 7, Color::rgb(255, 255, 0));

### OrbClient Drawing and Graphics Example

### Graphics drawing example in Rust (window.arc, circle, line, path, rect, etc.)

Source: https://docs.rs/orbclient/latest/orbclient/color/struct.Color.html?search=

A single Rust example (likely from a test or example program) that exercises many drawing primitives: arcs, circles, lines, bezier and quadratic paths (cloud and balloon), characters, pixel inspection, color comparison, rectangle modes (Blend/Overwrite), blur and shadow effects, and the event loop. The example runs inside a function that has access to 'window', 'width', 'height', 'start', and 'Color' types.

```rust
    window.arc(100, 100, -25, 1 << 4 | 1 << 6, Color::rgb(255, 0, 255));
    window.arc(100, 100, -25, 1 << 5 | 1 << 7, Color::rgb(255, 255, 0));
    window.circle(100, 100, 25, Color::rgb(0, 0, 0));
    window.circle(100, 101, -25, Color::rgb(0, 255, 0));
    window.circle(220, 220, -100, Color::rgba(128, 128, 128, 80));
    window.wu_circle(150, 220, 100, Color::rgba(255, 0, 0, 255));
    window.line(0, 0, 200, 200, Color::rgb(255, 0, 0));
    window.line(0, 200, 200, 0, Color::rgb(128, 255, 0));
    // vertical and horizontal line test
    window.line(100, 0, 100, 200, Color::rgb(0, 0, 255));
    window.line(0, 100, 200, 100, Color::rgb(255, 255, 0));
    window.wu_line(100, 220, 400, 250, Color::rgba(255, 0, 0, 255));
    window.line(100, 230, 400, 260, Color::rgba(255, 0, 0, 255));

    // path and bezier curve example draw a cloud
    let mut cloud_path = GraphicsPath::new();
    cloud_path.move_to(170, 80);
    cloud_path.bezier_curve_to(130, 100, 130, 150, 230, 150);
    cloud_path.bezier_curve_to(250, 180, 320, 180, 340, 150);

Source: https://docs.rs/orbclient/latest/orbclient/renderer/trait.Renderer.html?search=

Example from examples/simple.rs (line 100) showing how to draw characters using window.char with a specified color. The snippet includes window setup and event handling, and demonstrates drawing characters at positions (200,200) and (208,200).

```rust
fn main() {

    let mut window = Window::new_flags(
        (width as i32) / 4,

        width / 2,
        height / 2,
        "TITLE",
        &[WindowFlag::Transparent],

    window.char(208, 200, '═', Color::rgb(0, 0, 0));

    println!(
        "Drawing took {}ms",
        (start.elapsed().as_micros() / 100) as f32 / 10.0
    );

    window.sync();

    'events: loop {
        for event in window.events() {

Source: https://docs.rs/orbclient/latest/orbclient/event/struct.Event.html?search=Option%3CT%3E%2C+%28T+-%3E+U%29+-%3E+Option%3CU%3E

Basic usage example for `element_offset`, showing how to get the index of an element reference. Returns `None` if the element does not point to the start of an element.

```rust

let num = &nums[2];

assert_eq!(num, &1);
assert_eq!(nums.element_offset(num), Some(2));
