Struct ColorGenerator 

pub struct ColorGenerator { /* private fields */ }

Automatic color generator for creating visually distinct label colors.

ColorGenerator produces a sequence of pseudo-random colors that are perceptually distinct and readable. It’s useful for assigning colors to multiple labels automatically.

Examples

use musubi::{Report, ColorGenerator, Level};

let mut cg = ColorGenerator::new();

Report::new()
    // ...
    .with_label(0..3)
    .with_color(&cg.next_color())  // First color
    .with_label(4..5)
    .with_color(&cg.next_color())  // Second color (different)
    // ...

Implementations

impl ColorGenerator

pub fn new() -> Self

Create a new color generator with default brightness.

pub fn new_with_brightness(brightness: f32) -> Self

Create a new color generator with the specified brightness.

pub fn next_color(&mut self) -> GenColor

Generate the next color in the sequence.

Each call returns a different color code that is visually distinct from previous colors. The sequence is deterministic based on the initial state.

Examples

use musubi::ColorGenerator;

let mut cg = ColorGenerator::new();
let color1 = cg.next_color();
let color2 = cg.next_color();  // Different from color1
let color3 = cg.next_color();  // Different from color1 and color2

Trait Implementations

impl Default for ColorGenerator

fn default() -> Self

Returns the “default value” for a type.
