The structure servo uses to represent a stylesheet.

Fields

contents: StylesheetContents

The contents of this stylesheet.

shared_lock: SharedRwLock

The lock used for objects inside this stylesheet

media: Arc<Locked<MediaList>>

Methods

impl Stylesheet

pub fn from_bytes<R>(
    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<&StylesheetLoader>,
    error_reporter: &R,
    quirks_mode: QuirksMode
) -> Stylesheet where
    R: ParseErrorReporter, 

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

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

impl Stylesheet

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

Updates an empty stylesheet from a given string of text.

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

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.
