Struct Stylesheet

pub struct Stylesheet {
    pub contents: Arc<StylesheetContents>,
    pub shared_lock: SharedRwLock,
    pub media: Arc<Locked<MediaList>>,
    pub disabled: AtomicBool,
}

The structure servo uses to represent a stylesheet.

Fields

contents: Arc<StylesheetContents>

The contents of this stylesheet.

shared_lock: SharedRwLock

The lock used for objects inside this stylesheet

media: Arc<Locked<MediaList>>

List of media associated with the Stylesheet.

disabled: AtomicBool

Whether this stylesheet should be disabled.

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>, allow_import_rules: AllowImportRules, )

Updates an empty stylesheet from a given string of text.

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

Trait Implementations

impl Clone for Stylesheet

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Stylesheet

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl StylesheetInDocument for Stylesheet

fn media<'a>( &'a self, guard: &'a SharedRwLockReadGuard<'_>, ) -> Option<&'a MediaList>

Get the media associated with this stylesheet.

fn enabled(&self) -> bool

Get whether this stylesheet is enabled.

fn contents(&self) -> &StylesheetContents

Returns a reference to the contents of the stylesheet.

fn implicit_scope_root(&self) -> Option<ImplicitScopeRoot>

Return the implicit scope root for this stylesheet, if one exists.

fn rules<'a, 'b: 'a>( &'a self, guard: &'b SharedRwLockReadGuard<'_>, ) -> &'a [CssRule]

Returns a reference to the list of rules in this stylesheet.

fn iter_rules<'a, 'b, C>( &'a self, device: &'a Device, guard: &'a SharedRwLockReadGuard<'b>, ) -> RulesIterator<'a, 'b, C>

where C: NestedRuleIterationCondition,

Return an iterator using the condition C.

fn is_effective_for_device( &self, device: &Device, guard: &SharedRwLockReadGuard<'_>, ) -> bool

Returns whether the style-sheet applies for the current device.

fn effective_rules<'a, 'b>( &'a self, device: &'a Device, guard: &'a SharedRwLockReadGuard<'b>, ) -> EffectiveRulesIterator<'a, 'b>

Return an iterator over the effective rules within the style-sheet, as according to the supplied Device.
