Struct style::stylesheet_set::DocumentStylesheetSet

pub struct DocumentStylesheetSet<S>
where
    S: StylesheetInDocument + PartialEq + 'static,
{
    collections: PerOrigin<SheetCollection<S>>,
    invalidations: StylesheetInvalidationSet,
}

The set of stylesheets effective for a given document.

Fields

collections: PerOrigin<SheetCollection<S>>

The collections of sheets per each origin.

invalidations: StylesheetInvalidationSet

The invalidations for stylesheets added or removed from this document.

Implementations

impl<S> DocumentStylesheetSet<S>

where S: StylesheetInDocument + PartialEq + 'static,

pub fn new() -> Self

Create a new empty DocumentStylesheetSet.

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 len(&self) -> usize

Returns the number of stylesheets in the set.

pub fn sheet_count(&self, origin: Origin) -> usize

Returns the count of stylesheets for a given origin.

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

Returns the indexth stylesheet in the set for the given origin.

pub fn has_changed(&self) -> bool

Returns whether the given set has changed from the last flush.

pub fn flush<E>( &mut self, document_element: Option<E>, snapshots: Option<&SnapshotMap>, ) -> DocumentStylesheetFlusher<'_, S>

where E: TElement,

Flush the current set, unmarking it as dirty, and returns a DocumentStylesheetFlusher in order to rebuild the stylist.

pub fn flush_without_invalidation(&mut self) -> OriginSet

Flush stylesheets, but without running any of the invalidation passes.

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

Return an iterator over the flattened view of all the stylesheets.

pub fn force_dirty(&mut self, origins: OriginSet)

Mark the stylesheets for the specified origin as dirty, because something external may have invalidated it.

Trait Implementations

impl<S> MallocSizeOf for DocumentStylesheetSet<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.
