Enum LumaCoefficients 

#[non_exhaustive]
pub enum LumaCoefficients {
    Bt709,
    Bt601,
}

Luma coefficients for RGB→Gray conversion.

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.

Bt709

BT.709: 0.2126R + 0.7152G + 0.0722B (HDTV, sRGB).

Bt601

BT.601: 0.299R + 0.587G + 0.114B (SDTV, JPEG).

Trait Implementations

impl Clone for LumaCoefficients

fn clone(&self) -> LumaCoefficients

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LumaCoefficients

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

Formats the value using the given formatter.

impl Hash for LumaCoefficients

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

where __H: Hasher,

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 LumaCoefficients

fn eq(&self, other: &LumaCoefficients) -> 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.
