Enum ScreenshotContent 

pub enum ScreenshotContent {
    UiDominated {
        entropy: f32,
    },
    GameWorld {
        entropy: f32,
    },
    HighEntropy {
        entropy: f32,
    },
    Uniform {
        fill_value: u8,
    },
}

Screenshot content classification for optimal compression

Based on entropy analysis to determine best compression strategy.

Example

use jugar_probar::validators::ScreenshotContent;

// Simulate UI-heavy screenshot (low entropy)
let pixels: Vec<u8> = vec![255; 1000]; // Uniform white
let content = ScreenshotContent::classify(&pixels);

assert!(matches!(content, ScreenshotContent::Uniform { .. }));

Variants

UiDominated

UI-heavy (text, buttons) - high compressibility

Fields

entropy: f32

Shannon entropy (0.0-8.0 for bytes)

GameWorld

Physics/game world - medium compressibility

Fields

entropy: f32

Shannon entropy

HighEntropy

Random/noise - low compressibility

Fields

entropy: f32

Shannon entropy

Uniform

Mostly uniform - very high compressibility (same-fill)

Fields

fill_value: u8

Dominant fill value
