Struct style::stylesheets::import_rule::ImportRule

pub struct ImportRule {
    pub url: CssUrl,
    pub stylesheet: ImportSheet,
    pub supports: Option<ImportSupportsCondition>,
    pub layer: ImportLayer,
    pub source_location: SourceLocation,
}

The @import at-rule.

Fields

url: CssUrl

The <url> this @import rule is loading.

stylesheet: ImportSheet

The stylesheet is always present. However, in the case of gecko async parsing, we don’t actually have a Gecko sheet at first, and so the ImportSheet just has stub behavior until it appears.

supports: Option<ImportSupportsCondition>

A for the rule.

layer: ImportLayer

A layer() function name.

source_location: SourceLocation

The line and column of the rule’s source code.

Implementations

impl ImportRule

pub fn parse_layer_and_supports<'i, 't>( input: &mut Parser<'i, 't>, context: &mut ParserContext<'_>, ) -> (ImportLayer, Option<ImportSupportsCondition>)

Parses the layer() / layer / supports() part of the import header, as per https://drafts.csswg.org/css-cascade-5/#at-import:

[ layer | layer(<layer-name>) ]?
[ supports([ <supports-condition> | <declaration> ]) ]?

We do this here so that the import preloader can look at this without having to parse the whole import rule or parse the media query list or what not.
