Struct BlockLayout

pub struct BlockLayout {
    pub block_id: usize,
    pub position: usize,
    pub lines: Vec<LayoutLine>,
    pub y: f32,
    pub height: f32,
    pub top_margin: f32,
    pub bottom_margin: f32,
    pub left_margin: f32,
    pub right_margin: f32,
    pub list_marker: Option<ShapedListMarker>,
    pub base_direction: TextDirection,
    pub background_color: Option<[f32; 4]>,
}

Expand description

Computed layout for a single block (paragraph).

Fields§

§block_id: usize§position: usize

Document character position of the block start.

§lines: Vec<LayoutLine>

Laid out lines within the block.

§y: f32

Top edge relative to document start (set by flow layout).

§height: f32

Total height: top_margin + sum(line heights) + bottom_margin.

§top_margin: f32§bottom_margin: f32§left_margin: f32§right_margin: f32§list_marker: Option<ShapedListMarker>

Shaped list marker (positioned to the left of the content area). None if the block is not a list item.

§base_direction: TextDirection

The paragraph’s resolved base direction — never Auto.

BlockLayoutParams::base_direction may ask for auto-detection; this is what the bidi analysis actually settled on. Selection painting and caret motion need the answer, not the question.

§background_color: Option<[f32; 4]>

Block background color (RGBA). None means transparent.
