named color primaries

Named color primaries used to encode well-known sets of primaries. H.273 is the authority, when it comes to the exact values of primaries and authoritative specifications, where an equivalent code point exists.

A value of 0 is invalid and will never be present in the list of enums.

Descriptions do list the specifications for convenience.

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.

Trait Implementations

impl Clone for Primaries

fn clone(&self) -> Primaries

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Primaries

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

fn from(val: Primaries) -> u32

Converts to this type from the input type.

impl Hash for Primaries

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,

impl Ord for Primaries

fn cmp(&self, other: &Primaries) -> Ordering

This method returns an Ordering between self and other.
