Fields§

§collection: SheetCollection<S>

The actual style sheets.

§invalidations: StylesheetInvalidationSet

The set of invalidations scheduled for this collection.

Implementations§

source§

impl<S> AuthorStylesheetSet<S>where S: StylesheetInDocument + PartialEq + 'static,

source

pub fn new() -> Self

Create a new empty AuthorStylesheetSet.

source

pub fn dirty(&self) -> bool

Whether anything has changed since the last time this was flushed.

source

pub fn is_empty(&self) -> bool

Whether the collection is empty.

source

pub fn get(&self, index: usize) -> Option<&S>

Returns the indexth stylesheet in the collection of author styles if present.

source

pub fn len(&self) -> usize

Returns the number of author stylesheets.

source

fn collection_for(&mut self, _sheet: &S) -> &mut SheetCollection<S>

source

fn collect_invalidations_for( &mut self, device: Option<&Device>, sheet: &S, guard: &SharedRwLockReadGuard<'_> )

source

pub fn append_stylesheet( &mut self, device: Option<&Device>, sheet: S, guard: &SharedRwLockReadGuard<'_> )

Appends a new stylesheet to the current set.

No device implies not computing invalidations.

source

pub fn insert_stylesheet_before( &mut self, device: Option<&Device>, sheet: S, before_sheet: S, guard: &SharedRwLockReadGuard<'_> )

Insert a given stylesheet before another stylesheet in the document.

source

pub fn remove_stylesheet( &mut self, device: Option<&Device>, sheet: S, guard: &SharedRwLockReadGuard<'_> )

Remove a given stylesheet from the set.

source

pub fn rule_changed( &mut self, device: Option<&Device>, sheet: &S, rule: &CssRule, guard: &SharedRwLockReadGuard<'_>, change_kind: RuleChangeKind )

Notify the set that a rule from a given stylesheet has changed somehow.

source

pub fn iter(&self) -> StylesheetCollectionIterator<'_, S>

Iterate over the list of stylesheets.

source

pub fn force_dirty(&mut self)

Mark the sheet set dirty, as appropriate.

source

pub fn flush<E>( &mut self, host: Option<E>, snapshots: Option<&SnapshotMap> ) -> AuthorStylesheetFlusher<'_, S>where E: TElement,

Flush the stylesheets for this author set.

host is the root of the affected subtree, like the shadow host, for example.

Trait Implementations§

source§

impl<S> MallocSizeOf for AuthorStylesheetSet<S>where S: StylesheetInDocument + PartialEq + 'static + MallocSizeOf,

source§

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.
