Extension trait for drawing on a Buffer.

Required Methods

fn draw_horizontal_line(&mut self, x: u16, y: u16, width: u16, cell: Cell)

Draw a horizontal line of cells.

fn draw_vertical_line(&mut self, x: u16, y: u16, height: u16, cell: Cell)

Draw a vertical line of cells.

fn draw_rect_filled(&mut self, rect: Rect, cell: Cell)

Draw a filled rectangle.

fn draw_rect_outline(&mut self, rect: Rect, cell: Cell)

Draw a rectangle outline using a single cell character.

fn print_text(&mut self, x: u16, y: u16, text: &str, base_cell: Cell) -> u16

Print text at the given coordinates using the cell’s colors/attrs.

Characters replace the cell content; fg/bg/attrs come from base_cell. Stops at the buffer edge. Returns the x position after the last character.

fn print_text_clipped( &mut self, x: u16, y: u16, text: &str, base_cell: Cell, max_x: u16, ) -> u16

Print text with a right-side clipping boundary.

Like print_text but stops at max_x (exclusive) instead of the buffer edge. Returns the x position after the last character.

fn draw_border(&mut self, rect: Rect, chars: BorderChars, base_cell: Cell)

Draw a border around a rectangle using the given characters.

The border is drawn inside the rectangle (edges + corners). The cell’s fg/bg/attrs are applied to all border characters.

fn draw_box( &mut self, rect: Rect, chars: BorderChars, border_cell: Cell, fill_cell: Cell, )

Draw a border and fill the interior.

Draws a border using border_chars and fills the interior with fill_cell. If the rect is too small for an interior (width or height <= 2), only the border is drawn.

fn paint_area( &mut self, rect: Rect, fg: Option<PackedRgba>, bg: Option<PackedRgba>, )

Set all cells in a rectangular area to the given fg/bg/attrs without changing cell content.

Useful for painting backgrounds or selection highlights.
