The structure servo uses to represent a stylesheet.

Fields

contents: Arc<StylesheetContents>

The contents of this stylesheet.

Implementations

impl Stylesheet

pub fn from_bytes(
    bytes: &[u8],
    url_data: UrlExtraData,
    protocol_encoding_label: Option<&str>,
    environment_encoding: Option<&'static Encoding>,
    origin: Origin,
    media: MediaList,
    shared_lock: SharedRwLock,
    stylesheet_loader: Option<&dyn StylesheetLoader>,
    error_reporter: Option<&dyn ParseErrorReporter>,
    quirks_mode: QuirksMode
) -> Stylesheet

Parse a stylesheet from a set of bytes, potentially received over the network.

Takes care of decoding the network bytes and forwards the resulting string to Stylesheet::from_str.

pub fn update_from_bytes(
    existing: &Stylesheet,
    bytes: &[u8],
    protocol_encoding_label: Option<&str>,
    environment_encoding: Option<&'static Encoding>,
    url_data: UrlExtraData,
    stylesheet_loader: Option<&dyn StylesheetLoader>,
    error_reporter: Option<&dyn ParseErrorReporter>
)

Updates an empty stylesheet with a set of bytes that reached over the network.

impl Stylesheet

pub fn update_from_str(
    existing: &Stylesheet,
    css: &str,
    url_data: UrlExtraData,
    stylesheet_loader: Option<&dyn StylesheetLoader>,
    error_reporter: Option<&dyn ParseErrorReporter>,
    line_number_offset: u32,
    allow_import_rules: AllowImportRules
)

Updates an empty stylesheet from a given string of text.

fn parse_rules(
    css: &str,
    url_data: &UrlExtraData,
    origin: Origin,
    namespaces: &mut Namespaces,
    shared_lock: &SharedRwLock,
    stylesheet_loader: Option<&dyn StylesheetLoader>,
    error_reporter: Option<&dyn ParseErrorReporter>,
    quirks_mode: QuirksMode,
    line_number_offset: u32,
    use_counters: Option<&UseCounters>,
    allow_import_rules: AllowImportRules,
    sanitization_data: Option<&mut SanitizationData>
) -> (Vec<CssRule>, Option<String>, Option<String>)

pub fn from_str(
    css: &str,
    url_data: UrlExtraData,
    origin: Origin,
    media: Arc<Locked<MediaList>>,
    shared_lock: SharedRwLock,
    stylesheet_loader: Option<&dyn StylesheetLoader>,
    error_reporter: Option<&dyn ParseErrorReporter>,
    quirks_mode: QuirksMode,
    line_number_offset: u32,
    allow_import_rules: AllowImportRules
) -> Self

Creates an empty stylesheet and parses it with a given base url, origin and media.

Effectively creates a new stylesheet and forwards the hard work to Stylesheet::update_from_str.

pub fn disabled(&self) -> bool

Returns whether the stylesheet has been explicitly disabled through the CSSOM.

pub fn set_disabled(&self, disabled: bool) -> bool

Records that the stylesheet has been explicitly disabled through the CSSOM.

Returns whether the the call resulted in a change in disabled state.

Disabled stylesheets remain in the document, but their rules are not added to the Stylist.
