impl GenericImageSet<GenericImage<GenericGradient<LineDirection, LengthPercentage, NonNegative<Length>, NonNegative<LengthPercentage>, GenericPosition<PositionComponent<HorizontalPositionKeyword>, PositionComponent<VerticalPositionKeyword>>, Angle, AngleOrPercentage, Color>, CssUrl, Color, Percentage, Resolution>, Resolution>

fn parse<'i, 't>( context: &ParserContext<'_>, input: &mut Parser<'i, 't>, cors_mode: CorsMode, flags: ParseImageFlags, ) -> Result<Self, ParseError<'i>>

Trait Implementations

impl<Image: Clone, Resolution: Clone> Clone for GenericImageSet<Image, Resolution>

fn clone(&self) -> GenericImageSet<Image, Resolution>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<Image: Debug, Resolution: Debug> Debug for GenericImageSet<Image, Resolution>

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

Formats the value using the given formatter.

impl<Image, Resolution> MallocSizeOf for GenericImageSet<Image, Resolution>

where Image: MallocSizeOf, Resolution: 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<Image: PartialEq, Resolution: PartialEq> PartialEq for GenericImageSet<Image, Resolution>

fn eq(&self, other: &GenericImageSet<Image, Resolution>) -> 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<Image, Resolution> SpecifiedValueInfo for ImageSet<Image, Resolution>

const SUPPORTED_TYPES: u8 = 0u8

Supported CssTypes by the given value type.

fn collect_completion_keywords(f: KeywordsCollectFn<'_>)

Collect value starting words for the given specified value type. This includes keyword and function names which can appear at the beginning of a value of this type.

impl<Image, Resolution> ToCss for GenericImageSet<Image, Resolution>

where Image: ToCss, Resolution: ToCss,

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<Image, Resolution> ToResolvedValue for GenericImageSet<Image, Resolution>

where Image: ToResolvedValue, Resolution: ToResolvedValue,

type ResolvedValue = GenericImageSet<<Image as ToResolvedValue>::ResolvedValue, <Resolution as ToResolvedValue>::ResolvedValue>

The resolved value type we’re going to be converted to.

fn from_resolved_value(from: Self::ResolvedValue) -> Self

Convert a resolved value to resolved value form.

fn to_resolved_value(self, context: &Context<'_>) -> Self::ResolvedValue

Convert a resolved value to a resolved value.

impl<Image, Resolution> ToShmem for GenericImageSet<Image, Resolution>

where Image: ToShmem, Resolution: ToShmem,

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

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