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,
    _guard: &SharedRwLockReadGuard<'_>
) -> &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,
    S: 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.
