Function twenty_twenty::assert_image

pub fn assert_image<P: AsRef<Path>>(
    path: P,
    actual: &DynamicImage,
    min_permissible_similarity: f64
)

Compare the contents of the file to the image provided. If the two are less similar than the min_permissible_similarity threshold, the test will fail. The min_permissible_similarity is a float between 0 and 1. The score is a float between 0 and 1. If the images are the exact same, the score will be 1.
