Struct drm::mode::DumbBuf

pub struct DumbBuf { /* fields omitted */ }

Methods

impl DumbBuf

fn create(dev: &Device,
          width: u32,
          height: u32,
          bpp: u32,
          flags: DumbBufFlags)
          -> Result<DumbBuf>

Creates, maps and adds a dumb buf. I have not checked if it's wise to do all 3 or let the client deal with it. But it does mean we don't have to deal holding onto the device or the potential error of mapping on the wrong device.

unsafe fn handle(&self) -> u32

Not sure what this used for other than creating/mapping the frame buffer.

fn size(&self) -> (u32, u32)

(width, height) in pixels

fn bpp(&self) -> u32

Bits per pixel

fn pixel(&self) -> u32

Bytes per row

fn as_mut(&mut self) -> &mut [u8]

Access the buffer.

fn fb(&self) -> &Fb

Access the Fb object associated with this.
