Implementations

impl ColorFunction<AbsoluteColor>

pub fn resolve_to_absolute(&self) -> Result<AbsoluteColor, ()>

Try to resolve into a valid absolute color.

impl ColorFunction<Color>

pub fn has_origin_color(&self) -> bool

Return true if the color funciton has an origin color specified.

pub fn resolve_to_absolute(&self) -> Result<AbsoluteColor, ()>

Try to resolve the color function to an AbsoluteColor that does not contain any variables (currentcolor, color components, etc.).

impl<Color> ColorFunction<Color>

pub fn map_origin_color<U>( &self, f: impl FnOnce(&Color) -> Option<U>, ) -> ColorFunction<U>

Map the origin color to another type. Return None from f if the conversion fails.

impl ColorFunction<Color>

pub fn resolve_to_absolute( &self, current_color: &AbsoluteColor, ) -> AbsoluteColor

Resolve a computed color function to an absolute computed color.

Trait Implementations

impl<OriginColor: Clone> Clone for ColorFunction<OriginColor>

fn clone(&self) -> ColorFunction<OriginColor>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<OriginColor: Debug> Debug for ColorFunction<OriginColor>

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

Formats the value using the given formatter.

impl<OriginColor> MallocSizeOf for ColorFunction<OriginColor>

where OriginColor: MallocSizeOf,

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl<OriginColor: PartialEq> PartialEq for ColorFunction<OriginColor>

fn eq(&self, other: &ColorFunction<OriginColor>) -> 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<OriginColor> ToAnimatedValue for ColorFunction<OriginColor>

where OriginColor: ToAnimatedValue,

type AnimatedValue = ColorFunction<<OriginColor as ToAnimatedValue>::AnimatedValue>

The type of the animated value.

fn from_animated_value(from: Self::AnimatedValue) -> Self

Converts back an animated value into a computed value.

fn to_animated_value(self, context: &Context<'_>) -> Self::AnimatedValue

Converts this value to an animated value.

impl<C: ToCss> ToCss for ColorFunction<C>

fn to_css<W>(&self, dest: &mut CssWriter<'_, W>) -> Result

where 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.

impl<OriginColor> ToShmem for ColorFunction<OriginColor>

where OriginColor: ToShmem,

fn to_shmem(&self, builder: &mut SharedMemoryBuilder) -> Result<Self>

Clones this value into a form suitable for writing into a SharedMemoryBuilder.

impl<OriginColor> StructuralPartialEq for ColorFunction<OriginColor>
