Enum HueDirection

#[non_exhaustive]
#[repr(u8)]
pub enum HueDirection {
    Shorter = 0,
    Longer = 1,
    Increasing = 2,
    Decreasing = 3,
}

The hue direction for interpolation.

This type corresponds to hue-interpolation-method in the CSS Color 4 spec.

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.

Shorter = 0

Hue angles take the shorter of the two arcs between starting and ending values.

Longer = 1

Hue angles take the longer of the two arcs between starting and ending values.

Increasing = 2

Hue angles increase as they are interpolated.

Decreasing = 3

Hue angles decrease as they are interpolated.

Trait Implementations

impl CheckedBitPattern for HueDirection

type Bits = u8

Self must have the same layout as the specified Bits except for the possible invalid bit patterns being checked during is_valid_bit_pattern.

fn is_valid_bit_pattern(bits: &u8) -> bool

If this function returns true, then it must be valid to reinterpret bits as &Self.

impl Clone for HueDirection

fn clone(&self) -> HueDirection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Contiguous for HueDirection

const MIN_VALUE: u8 = 0u8

The lower inclusive bound for valid instances of this type.

const MAX_VALUE: u8 = 3u8

The upper inclusive bound for valid instances of this type.

type Int = u8

The primitive integer type with an identical representation to this type.

fn from_integer(value: Self::Int) -> Option<Self>

If value is within the range for valid instances of this type, returns Some(converted_value), otherwise, returns None.

fn into_integer(self) -> Self::Int

Perform the conversion from C into the underlying integral type. This mostly exists otherwise generic code would need unsafe for the value as integer

impl Debug for HueDirection

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

Formats the value using the given formatter.

impl Default for HueDirection

fn default() -> HueDirection

Returns the “default value” for a type.

impl PartialEq for HueDirection

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

impl Zeroable for HueDirection

fn zeroed() -> Self

Calls zeroed.

impl Copy for HueDirection

impl NoUninit for HueDirection

impl StructuralPartialEq for HueDirection
