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

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§

source§

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

source

pub fn new() -> Self

Create a new empty DocumentStylesheetSet.

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 len(&self) -> usize

Returns the number of stylesheets in the set.

source

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

Returns the count of stylesheets for a given origin.

source

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

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

source

pub fn has_changed(&self) -> bool

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

source

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.

source

pub fn flush_without_invalidation(&mut self) -> OriginSet

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

source

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

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

source

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§

source§

impl<S> MallocSizeOf for DocumentStylesheetSet<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.
