Struct TerminalWriter 

pub struct TerminalWriter { /* private fields */ }

Allows logging text to a pixel-based framebuffer.

Implementations

impl TerminalWriter

pub fn new(buffer: &'static mut [u8], info: FrameBufferInfo) -> Self

Creates a new logger that uses the given framebuffer.

pub fn newline(&mut self)

pub fn carriage_return(&mut self)

pub fn clear(&mut self)

Erases all text on the screen. Resets self.xpos and self.ypos.

pub fn width(&self) -> usize

pub fn height(&self) -> usize

pub fn write_char(&mut self, c: char)

Writes a single char to the framebuffer. Takes care of special control characters, such as newlines and carriage returns.

pub fn write_rendered_char(&mut self, rendered_char: RasterizedChar)

Prints a rendered char into the framebuffer. Updates self.xpos.

pub fn write_pixel(&mut self, x: usize, y: usize, intensity: u8)
