Struct StyleQuery

pub struct StyleQuery<'a> { /* private fields */ }

Represents node information, used for matching rules.

Implementations

impl<'a> StyleQuery<'a>

pub fn single( style_scope: Option<NonZeroUsize>, extra_style_scope: Option<NonZeroUsize>, host_style_scope: Option<NonZeroUsize>, tag_name: &'a str, id: &'a str, classes: &'a [(String, Option<NonZeroUsize>)], ) -> Self

Constructs a style query from tag name, id, classes, etc.
