pub struct Selector {
    pub selectors: SmallVec<[Selector<Simple>; 1]>,
}

Expand description

Wrapper around CSS selectors.

Represents a “selector group”, i.e. a comma-separated list of selectors.

Fields

selectors: SmallVec<[Selector<Simple>; 1]>

The CSS selectors.

Implementations

source

impl Selector

source

pub fn parse(
selectors: &str
) -> Result<Self, ParseError<'_, SelectorParseErrorKind<'_>>>

Parses a CSS selector group.

source

pub fn matches(&self, element: &ElementRef<'_>) -> bool

Returns true if the element matches this selector.

source

pub fn matches_with_scope(
 &self,
 element: &ElementRef<'_>,
 scope: Option<ElementRef<'_>>
) -> bool

Returns true if the element matches this selector. The optional scope argument is used to specify which element has :scope pseudo-class. When it is None, :scope will match the root element.
