Enum Subsampling 

#[non_exhaustive]
pub enum Subsampling {
    Mono,
    Yuv420,
    Yuv422,
    Yuv444,
}

Chroma subsampling of a planar picture.

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.

Mono

One plane, no chroma.

Yuv420

Chroma halved both ways.

Yuv422

Chroma halved horizontally.

Yuv444

Full-resolution chroma.

Implementations

impl Subsampling

pub const fn chroma_size(self, width: u32, height: u32) -> Option<(u32, u32)>
