Headless line information

Fields

logical_line_index: usize

Corresponding logical line index

is_wrapped_part: bool

Whether this is a part created by wrapping (soft wrap)

visual_in_logical: usize

Which wrapped segment within the logical line (0-based).

char_offset_start: usize

Character offset (inclusive) of this segment in the document.

char_offset_end: usize

Character offset (exclusive) of this segment in the document.

segment_x_start_cells: usize

Render x (in cells) where document text of this segment starts within the visual line.

For wrapped segments this is typically the wrap-indent cells.

is_fold_placeholder_appended: bool

Whether a fold placeholder was appended to this segment.

cells: Vec<Cell>

List of cells
