Implementations

impl VgaDisplay

fn new(framebuffer: Framebuffer) -> Self

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

pub fn clear(&mut self)

pub fn blit_inner_ranges( &mut self, src: (usize, usize), dest: (usize, usize), width: usize, height: usize )

pub fn blit( &mut self, src_buffer: &[u8], src_framebuffer_info: &FrameBufferInfo, src: (usize, usize), dest: (usize, usize), width: usize, height: usize )

unsafe fn blit_fast( &mut self, src_buffer: &[u8], src_framebuffer_info: &FrameBufferInfo, src: (usize, usize), dest: (usize, usize), width: usize, height: usize )

blit the src framebuffer to the current framebuffer fast here means that we assume the src and dest have the same format

fn blit_slow( &mut self, src_buffer: &[u8], src_framebuffer_info: &FrameBufferInfo, src: (usize, usize), dest: (usize, usize), width: usize, height: usize )

pub fn clear_rect( &mut self, dest_x: usize, dest_y: usize, width: usize, height: usize, color: Pixel )

Trait Implementations

impl DrawTarget for VgaDisplay

type Color = Rgb888

The pixel color type the targetted display supports.

type Error = ()

Error type to return when a drawing operation fails.

fn draw_iter<I>(&mut self, pixels: I) -> Result<(), Self::Error>

where I: IntoIterator<Item = Pixel<Self::Color>>,

Draw individual pixels to the display without a defined order.

fn fill_solid( &mut self, area: &Rectangle, color: Self::Color ) -> Result<(), Self::Error>

Fill a given area with a solid color.

fn clear(&mut self, color: Self::Color) -> Result<(), Self::Error>

Fill the entire display with a solid color.

fn fill_contiguous<I>( &mut self, area: &Rectangle, colors: I ) -> Result<(), Self::Error>

where I: IntoIterator<Item = Self::Color>,

Fill a given area with an iterator providing a contiguous stream of pixel colors.

impl OriginDimensions for VgaDisplay

fn size(&self) -> Size

Returns the size of the bounding box.
