Struct layout_2013::list_item::ListItemFlow

#[repr(C)]
pub struct ListItemFlow {
    pub block_flow: BlockFlow,
    pub marker_fragments: Vec<Fragment>,
}

A block with the CSS display property equal to list-item.

Fields

block_flow: BlockFlow

Data common to all block flows.

marker_fragments: Vec<Fragment>

The marker, if outside. (Markers that are inside are instead just fragments on the interior InlineFlow.)

Implementations

impl ListItemFlow

pub fn from_fragments_and_flotation( main_fragment: Fragment, marker_fragments: Vec<Fragment>, flotation: Option<FloatKind>, ) -> ListItemFlow

fn assign_marker_inline_sizes(&mut self, layout_context: &LayoutContext<'_>)

Assign inline size and position for the marker. This is done during the assign_block_size traversal because floats will impact the marker position. Therefore we need to have already called assign_block_size on the list item’s block flow, in order to know which floats impact the position.

Per CSS 2.1 § 12.5.1, the marker position is not precisely specified, but it must be on the left side of the content (for ltr direction). However, flowing the marker around floats matches the rendering of Gecko and Blink.

fn assign_marker_block_sizes(&mut self, layout_context: &LayoutContext<'_>)

Trait Implementations

impl Debug for ListItemFlow

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Flow for ListItemFlow

fn positioning(&self) -> Position

The ‘position’ property of this flow.

fn class(&self) -> FlowClass

Returns the class of flow that this is.

fn as_mut_block(&mut self) -> &mut BlockFlow

If this is a block flow, returns the underlying object, borrowed mutably. Fails otherwise.

fn as_block(&self) -> &BlockFlow

If this is a block flow, returns the underlying object. Fails otherwise.

fn bubble_inline_sizes(&mut self)

Pass 1 of reflow: computes minimum and preferred inline-sizes.

fn assign_inline_sizes(&mut self, layout_context: &LayoutContext<'_>)

Pass 2 of reflow: computes inline-size.

fn assign_block_size(&mut self, layout_context: &LayoutContext<'_>)

Pass 3a of reflow: computes block-size.

fn compute_stacking_relative_position( &mut self, layout_context: &LayoutContext<'_>, )

Phase 4 of reflow: Compute the stacking-relative position (origin of the content box, in coordinates relative to the nearest ancestor stacking context).

fn place_float_if_applicable<'a>(&mut self)

If this is a float, places it. The default implementation does nothing.

fn contains_roots_of_absolute_flow_tree(&self) -> bool

Returns true if this flow contains fragments that are roots of an absolute flow tree.

fn is_absolute_containing_block(&self) -> bool

Returns true if this is an absolute containing block.

fn update_late_computed_inline_position_if_necessary( &mut self, inline_position: Au, )

Updates the inline position of a child flow during the assign-height traversal. At present, this is only used for absolutely-positioned inline-blocks.

fn update_late_computed_block_position_if_necessary( &mut self, block_position: Au, )

Updates the block position of a child flow during the assign-height traversal. At present, this is only used for absolutely-positioned inline-blocks.

fn build_display_list(&mut self, state: &mut DisplayListBuildState<'_>)

Phase 5 of reflow: builds display lists.

fn collect_stacking_contexts( &mut self, state: &mut StackingContextCollectionState, )

fn repair_style(&mut self, new_style: &Arc<ComputedValues>)

Attempts to perform incremental fixup of this flow by replacing its fragment’s style with the new style. This can only succeed if the flow has exactly one fragment.

fn compute_overflow(&self) -> Overflow

Returns the union of all overflow rects of all of this flow’s fragments.

fn generated_containing_block_size(&self, flow: OpaqueFlow) -> LogicalSize<Au>

Return the size of the containing block generated by this flow for the absolutely- positioned descendant referenced by for_flow. For block flows, this is the padding box.

fn iterate_through_fragment_border_boxes( &self, iterator: &mut dyn FragmentBorderBoxIterator, level: i32, stacking_context_position: &Point2D<Au>, )

Iterates through border boxes of all of this flow’s fragments. Level provides a zero based index indicating the current depth of the flow tree during fragment iteration.

fn mutate_fragments(&mut self, mutator: &mut dyn FnMut(&mut Fragment))

Mutably iterates through fragments in this flow.

fn as_flex(&self) -> &FlexFlow

If this is a flex flow, returns the underlying object. Fails otherwise.

fn as_inline(&self) -> &InlineFlow

If this is an inline flow, returns the underlying object. Fails otherwise.

fn as_mut_inline(&mut self) -> &mut InlineFlow

If this is an inline flow, returns the underlying object, borrowed mutably. Fails otherwise.

fn as_table_wrapper(&self) -> &TableWrapperFlow

If this is a table wrapper flow, returns the underlying object. Fails otherwise.

fn as_mut_table(&mut self) -> &mut TableFlow

If this is a table flow, returns the underlying object, borrowed mutably. Fails otherwise.

fn as_table(&self) -> &TableFlow

If this is a table flow, returns the underlying object. Fails otherwise.

fn as_mut_table_colgroup(&mut self) -> &mut TableColGroupFlow

If this is a table colgroup flow, returns the underlying object, borrowed mutably. Fails otherwise.

fn as_table_colgroup(&self) -> &TableColGroupFlow

If this is a table colgroup flow, returns the underlying object. Fails otherwise.

fn as_mut_table_rowgroup(&mut self) -> &mut TableRowGroupFlow

If this is a table rowgroup flow, returns the underlying object, borrowed mutably. Fails otherwise.

fn as_table_rowgroup(&self) -> &TableRowGroupFlow

If this is a table rowgroup flow, returns the underlying object. Fails otherwise.

fn as_mut_table_row(&mut self) -> &mut TableRowFlow

If this is a table row flow, returns the underlying object, borrowed mutably. Fails otherwise.

fn as_table_row(&self) -> &TableRowFlow

If this is a table row flow, returns the underlying object. Fails otherwise.

fn as_mut_table_cell(&mut self) -> &mut TableCellFlow

If this is a table cell flow, returns the underlying object, borrowed mutably. Fails otherwise.

fn as_table_cell(&self) -> &TableCellFlow

If this is a table cell flow, returns the underlying object. Fails otherwise.

fn fragment( &mut self, layout_context: &LayoutContext<'_>, _fragmentation_context: Option<FragmentationContext>, ) -> Option<Arc<dyn Flow>>

Like assign_block_size, but is recurses explicitly into descendants. Fit as much content as possible within available_block_size. If that’s not all of it, truncate the contents of self and return a new flow similar to self with the rest of the content.

fn assign_block_size_for_inorder_child_if_necessary( &mut self, layout_context: &LayoutContext<'_>, parent_thread_id: u8, _content_box: LogicalRect<Au>, ) -> bool

Assigns block-sizes in-order; or, if this is a float, places the float. The default implementation simply assigns block-sizes if this flow might have floats in. Returns true if it was determined that this child might have had floats in or false otherwise.

fn has_non_invertible_transform_or_zero_scale(&self) -> bool

fn get_overflow_in_parent_coordinates(&self) -> Overflow

fn store_overflow(&mut self, _: &LayoutContext<'_>)

CSS Section 11.1 This is the union of rectangles of the flows for which we define the Containing Block.

fn mark_as_root(&mut self)

Marks this flow as the root flow. The default implementation is a no-op.

fn is_root(&self) -> bool

fn is_fixed(&self) -> bool

Return true if this flow has position ‘fixed’.

fn contains_positioned_fragments(&self) -> bool

fn contains_relatively_positioned_fragments(&self) -> bool

fn print_extra_flow_children(&self, _: &mut PrintTree)

Print any extra children (such as fragments) contained in this Flow for debugging purposes. Any items inserted into the tree will become children of this flow.

fn clipping_and_scrolling(&self) -> ClippingAndScrolling
