Struct Framebuffer 

pub struct Framebuffer {
    info: FramebufferInfo,
    pub canvas: CanvasBuffer,
    double_buffer: Option<*mut u8>,
    use_double_buffer: bool,
}

Main framebuffer structure

Fields

info: FramebufferInfo

canvas: CanvasBuffer

Shared double-buffered canvas (dirty tracking, present throttling, SIMD ops)

double_buffer: Option<*mut u8>

Raw double buffer for VirtIO GPU (physically contiguous)

use_double_buffer: bool

Whether the raw double buffer should be used

Implementations

impl Framebuffer

fn request_present(&mut self)

fn present_if_due(&mut self, force: bool)

pub fn init_limine( addr: u64, width: u32, height: u32, stride: u32, format: PixelFormat, ) -> Result<(), &'static str>

Initialize framebuffer with Limine-provided buffer

pub fn init_virtio_gpu() -> Result<(), &'static str>

Initialize framebuffer with VirtIO GPU

pub fn info() -> Option<FramebufferInfo>

Get framebuffer info

pub fn width() -> u32

Get framebuffer width

pub fn height() -> u32

Get framebuffer height

pub fn stride() -> u32

Get stride (bytes per row)

pub fn is_available() -> bool

Check if framebuffer is initialized

pub fn source() -> FramebufferSource

Get framebuffer source

pub fn render_stats() -> Option<FramebufferRenderStats>

pub fn set_pixel(x: u32, y: u32, r: u8, g: u8, b: u8)

Set a pixel at (x, y) with RGB color.

Does NOT present to screen. Call swap_buffers() or present() after a batch of draw operations.

pub fn fill_rect(x: u32, y: u32, width: u32, height: u32, r: u8, g: u8, b: u8)

Fill rectangle with color.

Does NOT present to screen. Call swap_buffers() or present() after a batch of draw operations.

pub fn draw_hline(x: u32, y: u32, length: u32, r: u8, g: u8, b: u8)

Draw a horizontal line

pub fn draw_vline(x: u32, y: u32, length: u32, r: u8, g: u8, b: u8)

Draw a vertical line

pub fn clear()

Clear screen to black

pub fn swap_buffers()

Swap buffers (for double buffering)

pub fn set_double_buffering(enable: bool)

Enable/disable double buffering
