Enum Subsampling 

#[non_exhaustive]
pub enum Subsampling {
    S444,
    S422,
    S420,
    S440,
}

Chroma subsampling mode.

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.

S444

4:4:4 - No subsampling

S422

4:2:2 - Horizontal subsampling only

S420

4:2:0 - Both horizontal and vertical subsampling

S440

4:4:0 - Vertical subsampling only (rare)

Implementations

impl Subsampling

pub const fn h_samp_factor_luma(self) -> u8

Returns the horizontal sampling factor for luma.

pub const fn v_samp_factor_luma(self) -> u8

Returns the vertical sampling factor for luma.

Trait Implementations

impl Clone for Subsampling

fn clone(&self) -> Subsampling

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Subsampling

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Subsampling

fn default() -> Subsampling

Returns the “default value” for a type.

impl Hash for Subsampling

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Subsampling

fn eq(&self, other: &Subsampling) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
