Implementations

impl QueryStyleRange

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

Parses the following range syntax:

value value value value value

This is only used when parsing @container style() queries; the feature_type and index is hardcoded (and ignored).

pub fn evaluate(&self, context: &Context<'_>) -> KleeneValue

Returns whether this style-range query evaluates to true for the given context.

fn resolve_value( value: &QueryExpressionValue, context: &Context<'_>, visited_set: &mut PrecomputedHashSet<DashedIdent>, ) -> Option<Component>

fn resolve_universal( css_text: &str, url_data: &UrlExtraData, context: &Context<'_>, visited_set: &mut PrecomputedHashSet<DashedIdent>, ) -> Option<Component>

fn compare_values( value1: Option<&Component>, value2: Option<&Component>, ) -> Option<Ordering>

Trait Implementations

impl Clone for QueryStyleRange

fn clone(&self) -> QueryStyleRange

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QueryStyleRange

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

Formats the value using the given formatter.

impl MallocSizeOf for QueryStyleRange

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 PartialEq for QueryStyleRange

fn eq(&self, other: &QueryStyleRange) -> 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 ToCss for QueryStyleRange

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.

fn to_css_cssstring(&self) -> String

Serialize self in CSS syntax and return a CssString.

impl ToShmem for QueryStyleRange

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

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