Struct layout_2020::flow::inline::line::LineItemLayout

pub(super) struct LineItemLayout<'layout_data, 'layout> {
    layout: &'layout mut InlineFormattingContextLayout<'layout_data>,
    pub state_stack: Vec<LineItemLayoutInlineContainerState>,
    pub current_state: LineItemLayoutInlineContainerState,
    pub line_metrics: LineMetrics,
    pub justification_adjustment: Au,
}

The second phase of super::InlineFormattingContext layout: once items are gathered for a line, we must lay them out and create fragments for them, properly positioning them according to their baselines and also handling absolutely positioned children.

Fields

layout: &'layout mut InlineFormattingContextLayout<'layout_data>

The state of the overall super::InlineFormattingContext layout.

state_stack: Vec<LineItemLayoutInlineContainerState>

The set of LineItemLayoutInlineContainerState created while laying out items on this line. This does not include the current level of recursion.

current_state: LineItemLayoutInlineContainerState

The current LineItemLayoutInlineContainerState.

line_metrics: LineMetrics

The metrics of this line, which should remain constant throughout the layout process.

justification_adjustment: Au

The amount of space to add to each justification opportunity in order to implement text-align: justify.
