Struct BrailleCanvas 

pub struct BrailleCanvas { /* private fields */ }

Braille-dot terminal canvas: each character cell packs a 2x4 grid of dots into one Unicode Braille Patterns codepoint.

Implementations

impl BrailleCanvas

pub fn new(width_cells: usize, height_cells: usize) -> Self

pub fn width_dots(&self) -> usize

pub fn height_dots(&self) -> usize

pub fn set(&mut self, x: usize, y: usize)

Turn on the dot at dot-coordinate (x, y); (0, 0) is top-left. Coordinates outside the canvas are silently dropped.

pub fn render(&self) -> String

Render to a string of height_cells lines, each width_cells characters wide (no trailing newline). A cell with no dots set renders as U+2800 (BRAILLE PATTERN BLANK), not an ASCII space — it is a real glyph, not empty output.
