Struct hanbun::Buffer

pub struct Buffer {
    pub cells: Vec<Cell>,
    pub width: usize,
    pub height: usize,
    // some fields omitted
}

A buffer for storing the state of the cells. You can see it as a drawing canvas.

Examples

let mut buffer;

if let Ok((width, height)) = hanbun::size() {
    buffer = hanbun::Buffer::new(width, height, ' ');
} else {
    return;
}

buffer.set(3, 3);
buffer.draw();

Fields

cells: Vec<Cell>

width: usize

height: usize

Implementations

impl Buffer

pub fn new(width: usize, height: usize, char: char) -> Buffer

Creates a new buffer of width * height cells filled with char.

pub fn draw(&mut self)

Draws the buffer to the screen.

Panics

Panics if an internal write operation operation failed.

pub fn clear(&mut self, char: char)

Clears the buffer using char.

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

Sets the cell at (x, y) to a half block.

Panics

Panics if (x, y) is out of the buffer’s range.

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

Colors the cell at (x, y) with the given color.

Panics

Panics if (x, y) is out of the buffer’s range.

pub fn print(&mut self, x: usize, y: usize, string: &str)

Prints string to (x, y).

Panics

Panics if (x, y) is out of the buffer’s range.
