Implementations

impl SimpleDisplayAdapter

pub fn new(virt: usize, width: u32, height: u32, stride: u32, bpp: u8) -> Self

Create from an existing framebuffer.

pub fn from_framebuffer() -> Option<Self>

Create from the global Framebuffer if available.

Trait Implementations

impl GraphicsAdapter for SimpleDisplayAdapter

type Screen = HeapScreen

The screen type created by this adapter.

fn display_count(&self) -> usize

Number of connected displays.

fn display_size(&self, display_id: usize) -> (u32, u32)

Resolution of a specific display.

fn create_framebuffer(&self, width: u32, height: u32) -> HeapScreen
