Struct OptionColor 

pub struct OptionColor<COL> {
    pub color: Option<COL>,
}

Wrapper for optional color values with style fallback.

This struct provides a convenient way to handle optional color parameters in widgets. When a color is not explicitly set, it falls back to the corresponding color from the global style configuration.

Type Parameters

• COL - The pixel color type implementing PixelColor

Example

use matrix_gui::prelude::*;

// Create with no color set
let mut color = OptionColor::none();

// Set a specific color
color.set_color(Rgb565::RED);

Fields

color: Option<COL>

The optional color value.
