Struct UefiDisplay

pub struct UefiDisplay<'a> { /* private fields */ }

UEFI Display driver. This assumes Rgb888 pixel formatting.

Implementations

impl<'a> UefiDisplay<'a>

pub fn new<T>( fb: *mut u8, stride: u32, size: (u32, u32), _lifetime: &'a T, ) -> Self

Create a new UefiDisplay.

fb must be the UEFI framebuffer base, and stride the pixel stride, and size the horizontal and vertical resolution, respectively.

In the UEFI spec this information is found in the EFI_GRAPHICS_OUTPUT_MODE_INFORMATION structure.

T is something providing a lifetime for fb. If your UEFI API does not provide a lifetime, &() should work.

Trait Implementations

impl<'a> DrawTarget for UefiDisplay<'a>

type Color = Rgb888

The pixel color type the targetted display supports.

type Error = Unsupported

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_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.

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.

impl<'a> OriginDimensions for UefiDisplay<'a>

fn size(&self) -> Size

Return the size of the display
