Expand description

Parameters extracted from text-document’s BlockFormat / TextFormat. This is a plain struct so block layout doesn’t depend on text-document types.

Fields§

§block_id: usize§position: usize§text: String§fragments: Vec<FragmentParams>§alignment: Alignment§top_margin: f32§bottom_margin: f32§left_margin: f32§right_margin: f32§text_indent: f32§list_marker: String

List marker text (e.g., “1.”, “•”, “a)”). Empty if not a list item.

§list_indent: f32

Additional left indent for list items (in pixels).

§tab_positions: Vec<f32>

Tab stop positions in pixels from the left margin.

§line_height_multiplier: Option<f32>

Line height multiplier. 1.0 = normal (from font metrics), 1.5 = 150%, 2.0 = double. None means use font metrics (ascent + descent + leading).

§non_breakable_lines: bool

If true, prevent line wrapping. The entire block is one long line.

§checkbox: Option<bool>

Checkbox marker: None = no checkbox, Some(false) = unchecked, Some(true) = checked.

§background_color: Option<[f32; 4]>
