Struct lightningcss::rules::style::StyleRule

pub struct StyleRule<'i, R = DefaultAtRule> {
    pub selectors: SelectorList<'i>,
    pub vendor_prefix: VendorPrefix,
    pub declarations: DeclarationBlock<'i>,
    pub rules: CssRuleList<'i, R>,
    pub loc: Location,
}

A CSS style rule.

Fields

selectors: SelectorList<'i>

The selectors for the style rule.

vendor_prefix: VendorPrefix

A vendor prefix override, used during selector printing.

declarations: DeclarationBlock<'i>

The declarations within the style rule.

rules: CssRuleList<'i, R>

Nested rules within the style rule.

loc: Location

The location of the rule in the source file.

Implementations

impl<'i, T> StyleRule<'i, T>

pub fn is_empty(&self) -> bool

Returns whether the rule is empty.

pub fn is_compatible(&self, targets: Option<Browsers>) -> bool

Returns whether the selectors in the rule are compatible with all of the given browser targets.

pub fn property_location<'t>(
    &self,
    code: &'i str,
    index: usize
) -> Result<(Range<SourceLocation>, Range<SourceLocation>), ParseError<'i, ParserError<'i>>>

Returns the line and column range of the property key and value at the given index in this style rule.

For performance and memory efficiency in non-error cases, source locations are not stored during parsing. Instead, they are computed lazily using the original source string that was used to parse the stylesheet/rule.

Trait Implementations

impl<'i, R: Clone> Clone for StyleRule<'i, R>

fn clone(&self) -> StyleRule<'i, R>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'i, R: Debug> Debug for StyleRule<'i, R>

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

Formats the value using the given formatter.

impl<'i, R: PartialEq> PartialEq<StyleRule<'i, R>> for StyleRule<'i, R>

fn eq(&self, other: &StyleRule<'i, R>) -> 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<'i, R, __V: Visitor<'i, R>> Visit<'i, R, __V> for StyleRule<'i, R>where
    R: Visit<'i, R, __V>,

const CHILD_TYPES: VisitTypes = _

The types of values contained within this value and its children. This is used to skip branches that don’t have any values requested by the Visitor.

fn visit_children(&mut self, visitor: &mut __V)

Visit the children of this value.

fn visit(&mut self, visitor: &mut V)

Visits the value by calling an appropriate method on the Visitor. If no corresponding visitor method exists, then the children are visited.
