Struct Object 

pub struct Object<T: DriverObject, C: DeviceContext = Registered> { /* private fields */ }

A shmem-backed GEM object.

Invariants

• obj contains a valid initialized struct drm_gem_shmem_object for the lifetime of this object.
• Any type invariants of C apply to the parent DRM device for this GEM object.

Implementations

impl<T: DriverObject, C: DeviceContext> Object<T, C>

pub fn project<'__pin>( self: Pin<&'__pin mut Self>, ) -> ObjectProjection<'__pin, T, C>

Pin-projects all fields of Self.

These fields are structurally pinned:

• obj
• inner

These fields are not structurally pinned:

• parent_resv_obj
• _ctx

impl<T: DriverObject, C: DeviceContext> Object<T, C>

pub fn new( dev: &Device<T::Driver, C>, size: usize, config: ObjectConfig<'_, T, C>, args: T::Args, ) -> Result<ARef<Self>>

Create a new shmem-backed DRM object of the given size.

Additional config options can be specified using config.

pub fn dev(&self) -> &Device<T::Driver, C>

Returns the Device that owns this GEM object.

Trait Implementations

impl<T: DriverObject, C: DeviceContext> AllocImpl for Object<T, C>

const ALLOC_OPS: AllocOps

The C callback operations for this memory manager.

type Driver = <T as DriverObject>::Driver

The Driver implementation for this AllocImpl.

impl<T, C> AlwaysRefCounted for Object<T, C>

where Self: IntoGEMObject, T: DriverObject, C: DeviceContext,

fn inc_ref(&self)

Increments the reference count on the object.

unsafe fn dec_ref(obj: NonNull<Self>)

Decrements the reference count on the object.

impl<T: DriverObject, C: DeviceContext> Deref for Object<T, C>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<T: DriverObject, C: DeviceContext> DerefMut for Object<T, C>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl<T: DriverObject, C: DeviceContext> HasPinData for Object<T, C>

type PinData = __ThePinData<T, C>

unsafe fn __pin_data() -> Self::PinData

impl<T: DriverObject, C: DeviceContext> IntoGEMObject for Object<T, C>

fn as_raw(&self) -> *mut drm_gem_object

Returns a reference to the raw drm_gem_object structure, which must be valid as long as this owning object is valid.

unsafe fn from_raw<'a>(obj: *mut drm_gem_object) -> &'a Self

Converts a pointer to a struct drm_gem_object into a reference to Self.
