Struct gbm::MappedBufferObject

pub struct MappedBufferObject<'a, T: 'static> { /* fields omitted */ }

A read-only mapped buffer object

Methods from Deref<Target = BufferObject<'a, T>>

fn width(&self) -> u32

Get the width of the buffer object

fn height(&self) -> u32

Get the height of the buffer object

fn stride(&self) -> u32

Get the stride of the buffer object

fn format(&self) -> Format

Get the format of the buffer object

fn handle(&self) -> BufferObjectHandle

Get the handle of the buffer object

This is stored in the platform generic union BufferObjectHandle type. However the format of this handle is platform specific.

fn map(
    &'a self,
    x: u32,
    y: u32,
    width: u32,
    height: u32
) -> IoResult<MappedBufferObject<'a, T>>

Map a region of a gbm buffer object for cpu access

This function maps a region of a gbm bo for cpu read access.

fn userdata(&self) -> Option<&T>

Returns a reference to set userdata, if any.
