Enum ChromaSubsampling 

#[non_exhaustive]
pub enum ChromaSubsampling {
    Yuv420,
    Yuv444,
}

How an encoder samples chroma (sharp’s chromaSubsampling).

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.

Yuv420

Chroma at half resolution both ways ('4:2:0'): smaller files, and a loss photographs rarely show.

Yuv444

Chroma at full resolution ('4:4:4'): edges between colours, as in screenshots and text, stay sharp.
