Fields

text_segments: Vec<String>

The collection of text strings that make up this InlineFormattingContext under construction.

current_text_offset: usize

The current offset in the final text string of this InlineFormattingContext, used to properly set the text range of new InlineItem::TextRuns.

last_inline_box_ended_with_collapsible_white_space: bool

Whether the last processed node ended with whitespace. This is used to implement rule 4 of https://www.w3.org/TR/css-text-3/#collapse:

Any collapsible space immediately following another collapsible space—even one outside the boundary of the inline containing that space, provided both spaces are within the same inline formatting context—is collapsed to have zero advance width. (It is invisible, but retains its soft wrap opportunity, if any.)

on_word_boundary: bool

Whether or not the current state of the inline formatting context is on a word boundary for the purposes of text-transform: capitalize.

contains_floats: bool

Whether or not this inline formatting context will contain floats.

inline_items: Vec<ArcRefCell<InlineItem>>

The current list of InlineItems in this InlineFormattingContext under construction. This is stored in a flat list to make it easy to access the last item.

inline_boxes: InlineBoxes

The current InlineBox tree of this InlineFormattingContext under construction.

inline_box_stack: Vec<InlineBoxIdentifier>

The ongoing stack of inline boxes stack of the builder.

Contains all the currently ongoing inline boxes we entered so far. The traversal is at all times as deep in the tree as this stack is, which is why the code doesn’t need to keep track of the actual container root (see handle_inline_level_element).

When an inline box ends, it’s removed from this stack.

has_uncollapsible_text_content: bool

Whether or not the inline formatting context under construction has any uncollapsible text content.

Implementations

impl InlineFormattingContextBuilder

pub(crate) fn new() -> Self

pub(crate) fn currently_processing_inline_box(&self) -> bool

fn push_control_character_string(&mut self, string_to_push: &str)

pub(crate) fn is_empty(&self) -> bool

Return true if this InlineFormattingContextBuilder is empty for the purposes of ignoring during box tree construction. An IFC is empty if it only contains TextRuns with completely collapsible whitespace. When that happens it can be ignored completely.

pub(crate) fn push_atomic( &mut self, independent_formatting_context: IndependentFormattingContext, ) -> ArcRefCell<InlineItem>

pub(crate) fn push_absolutely_positioned_box( &mut self, absolutely_positioned_box: AbsolutelyPositionedBox, ) -> ArcRefCell<InlineItem>

pub(crate) fn push_float_box( &mut self, float_box: FloatBox, ) -> ArcRefCell<InlineItem>

pub(crate) fn start_inline_box(&mut self, inline_box: InlineBox)

pub(crate) fn end_inline_box(&mut self) -> ArcRefCell<InlineBox>

fn end_inline_box_internal(&mut self) -> InlineBoxIdentifier

pub(crate) fn push_text<'dom, Node: NodeExt<'dom>>( &mut self, text: Cow<'dom, str>, info: &NodeAndStyleInfo<Node>, )

pub(crate) fn split_around_block_and_finish( &mut self, layout_context: &LayoutContext<'_>, text_decoration_line: TextDecorationLine, has_first_formatted_line: bool, default_bidi_level: Level, ) -> Option<InlineFormattingContext>

pub(crate) fn finish( &mut self, layout_context: &LayoutContext<'_>, text_decoration_line: TextDecorationLine, has_first_formatted_line: bool, is_single_line_text_input: bool, default_bidi_level: Level, ) -> Option<InlineFormattingContext>

Finish the current inline formatting context, returning None if the context was empty.

Trait Implementations

impl Default for InlineFormattingContextBuilder

fn default() -> InlineFormattingContextBuilder

Returns the “default value” for a type.
