Struct StarfieldGenerator 

pub struct StarfieldGenerator {
    pub stars: Vec<Star>,
}

A procedural generator for rendering cosmic starfields and bokeh onto image backgrounds.

Fields

stars: Vec<Star>

The collection of active star elements.

Implementations

impl StarfieldGenerator

pub fn random(monitor: &Monitor) -> WallSwitchResult<Self>

Generates a randomized field of stars based on the monitor’s physical dimensions.

Reuses new internally to construct the star positions and color properties.

Errors

Returns WallSwitchError::EmptySlice if the global neon palette table is empty.

pub fn new(count: usize, width: u64, height: u64) -> WallSwitchResult<Self>

Generates a randomized field of stars using the centralized high-contrast neon colors.

Errors

Returns WallSwitchError::EmptySlice if the global neon palette table is empty.

Trait Implementations

impl ImageEffect for StarfieldGenerator

fn apply(&self, rgb_img: &mut RgbImage)

Blends the generated starfield overlay onto the image buffer in parallel.

fn info(&self) -> String

Returns a formatting diagnostic string about the active generator.

fn apply_effect( &self, input_path: &Path, output_path: &Path, ) -> WallSwitchResult<()>

Convenience helper: opens input_path, runs the effect, writes output_path.
