Implementations

impl Color

pub fn parse<'i>( input: &mut Parser<'i, '_> ) -> Result<Color, ParseError<'i, ()>>

Parse a value, per CSS Color Module Level 3.

FIXME(#2) Deprecated CSS2 System Colors are not supported yet.

Trait Implementations

impl Clone for Color

fn clone(&self) -> Color

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Color

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

Formats the value using the given formatter.

impl FromParsedColor for Color

fn from_current_color() -> Self

Construct a new color from the CSS currentcolor keyword.

fn from_rgba( red: Option<u8>, green: Option<u8>, blue: Option<u8>, alpha: Option<f32> ) -> Self

Construct a new color from red, green, blue and alpha components.

fn from_hsl( hue: Option<f32>, saturation: Option<f32>, lightness: Option<f32>, alpha: Option<f32> ) -> Self

Construct a new color from hue, saturation, lightness and alpha components.

fn from_hwb( hue: Option<f32>, blackness: Option<f32>, whiteness: Option<f32>, alpha: Option<f32> ) -> Self

Construct a new color from hue, blackness, whiteness and alpha components.

fn from_lab( lightness: Option<f32>, a: Option<f32>, b: Option<f32>, alpha: Option<f32> ) -> Self

Construct a new color from the lab notation.

Construct a new color from the lch notation.

fn from_oklab( lightness: Option<f32>, a: Option<f32>, b: Option<f32>, alpha: Option<f32> ) -> Self

Construct a new color from the oklab notation.

fn from_oklch( lightness: Option<f32>, chroma: Option<f32>, hue: Option<f32>, alpha: Option<f32> ) -> Self

impl PartialEq<Color> for Color

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl ToCss for Color

fn to_css<W>(&self, dest: &mut W) -> Resultwhere W: Write,

Serialize self in CSS syntax, writing to dest.

fn to_css_string(&self) -> String

Serialize self in CSS syntax and return a string.
