Struct VisualDiff 

pub struct VisualDiff {
    pub perceptual_similarity: f64,
    pub pixel_diff_count: u64,
    pub diff_regions: Vec<DiffRegion>,
    pub expected: Option<Vec<u8>>,
    pub actual: Vec<u8>,
    pub highlighted: Vec<u8>,
}

Visual comparison result using perceptual hash

Per Shamir [19]: pHash more robust than SHA-256 for game frame comparison

Fields

perceptual_similarity: f64

Perceptual similarity (0.0 to 1.0)

pixel_diff_count: u64

Pixel-level difference count

diff_regions: Vec<DiffRegion>

Highlighted regions that differ

expected: Option<Vec<u8>>

Expected image data (if available)

actual: Vec<u8>

Actual image data

highlighted: Vec<u8>

Diff overlay image

Implementations

impl VisualDiff

pub fn new(similarity: f64, actual: Vec<u8>) -> Self

pub fn matches(&self, threshold: f64) -> bool

Check if images match within threshold

pub fn is_identical(&self) -> bool

Check if images are identical
