}

A set of box-drawing characters. Mirrors rich.box.Box.

The field names match upstream’s 8×4 grid:

top_left    top              top_divider     top_right
head_left   (space)          head_vertical   head_right
head_row_left head_row_horizontal head_row_cross head_row_right
mid_left    (space)          mid_vertical    mid_right
row_left    row_horizontal   row_cross       row_right
foot_row_left foot_row_horizontal foot_row_cross foot_row_right
foot_left   (space)          foot_vertical   foot_right
bottom_left bottom           bottom_divider  bottom_right

Implementations

impl Box

pub fn get_top(&self, widths: &[usize], edge: bool) -> String

The top border for the given column widths. Port of Box.get_top. edge controls whether the left/right corner glyphs are drawn.

pub fn get_row(&self, widths: &[usize], level: RowLevel, edge: bool) -> String

A horizontal divider row between columns at a given level. Port of Box.get_row. edge controls whether the left/right glyphs are drawn.

pub fn substitute( &self, legacy_windows: bool, safe: bool, ascii_only: bool, ) -> Box

Return a version of this box safe for the target terminal. Port of Box.substitute.

On a legacy Windows console (legacy_windows + safe), the fancy boxes that legacy code pages can’t draw — ROUNDED, HEAVY, HEAVY_HEAD — fall back to SQUARE (DOUBLE/SQUARE/MINIMAL are kept). On a non-UTF-8 terminal (ascii_only), any non-ASCII box becomes ASCII.

pub fn get_bottom(&self, widths: &[usize], edge: bool) -> String

The bottom border for the given column widths. Port of Box.get_bottom. edge controls whether the left/right corner glyphs are drawn.
