Enum Dither 

#[non_exhaustive]
pub enum Dither {
    None,
    Bayer,
    FloydSteinberg,
}

Dither strategy used when -colors N forces a paletted output.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
