Fields

inline_items: Vec<InlineItem>

All InlineItems in this InlineFormattingContext stored in a flat array. InlineItem::StartInlineBox and InlineItem::EndInlineBox allow representing the tree of inline boxes within the formatting context, but a flat array allows easy iteration through all inline items.

inline_boxes: InlineBoxes

The tree of inline boxes in this InlineFormattingContext. These are stored in a flat array with each being given a InlineBoxIdentifier.

text_content: String

The text content of this inline formatting context.

shared_inline_styles: SharedInlineStyles

The SharedInlineStyles for the root of this InlineFormattingContext that are used to share styles with all TextRun children.

default_font: Option<FontRef>

The default font that is used for the root of this InlineFormattingContext. This is the font used when the font fallback code path is not taken. It may be None if no default font was found (this typically means that no characters can be rendered).

has_first_formatted_line: bool

Whether this IFC contains the 1st formatted line of an element: https://www.w3.org/TR/css-pseudo-4/#first-formatted-line.

contains_floats: bool

Whether or not this InlineFormattingContext contains floats.

is_single_line_text_input: bool

Whether or not this is an InlineFormattingContext for a single line text input’s inner text container.

has_right_to_left_content: bool

Whether or not this is an InlineFormattingContext has right-to-left content, which will require reordering during layout.

shared_selection: Option<SharedSelection>

If this InlineFormattingContext has a selection shared with its originating node in the DOM, this will not be None.

tab_stop_advance: OnceLock<Au>

The cached tab stop inline advance used when finding final tab stops for preserved tabs.

Trait Implementations

impl ComputeInlineContentSizes for InlineFormattingContext

fn compute_inline_content_sizes( &self, layout_context: &LayoutContext<'_>, constraint_space: &ConstraintSpace<'_>, ) -> InlineContentSizesResult

fn compute_inline_content_sizes_with_fixup( &self, layout_context: &LayoutContext<'_>, constraint_space: &ConstraintSpace<'_>, ) -> InlineContentSizesResult

Returns the same result as Self::compute_inline_content_sizes(), but adjusted to floor the max-content size by the min-content size. This is being discussed in https://github.com/w3c/csswg-drafts/issues/12076.

impl Debug for InlineFormattingContext

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

Formats the value using the given formatter.

impl MallocSizeOf for InlineFormattingContext

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.
