Struct style::stylesheet_set::AuthorStylesheetSet

pub struct AuthorStylesheetSet<S>
where
    S: StylesheetInDocument + PartialEq + 'static,
{
    collection: SheetCollection<S>,
    invalidations: StylesheetInvalidationSet,
}

The set of stylesheets effective for a given Shadow Root.

Fields

collection: SheetCollection<S>

The actual style sheets.

invalidations: StylesheetInvalidationSet

The set of invalidations scheduled for this collection.

Implementations

impl<S> AuthorStylesheetSet<S>

where S: StylesheetInDocument + PartialEq + 'static,

pub fn new() -> Self

Create a new empty AuthorStylesheetSet.

pub fn dirty(&self) -> bool

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

pub fn is_empty(&self) -> bool

Whether the collection is empty.

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

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

pub fn len(&self) -> usize

Returns the number of author stylesheets.

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

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

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.

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.

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

Remove a given stylesheet from the set.

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.

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

Iterate over the list of stylesheets.

pub fn force_dirty(&mut self)

Mark the sheet set dirty, as appropriate.

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

impl<S> MallocSizeOf for AuthorStylesheetSet<S>

where S: StylesheetInDocument + PartialEq + 'static + MallocSizeOf,

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.
