Struct Object

#[repr(C)]
pub struct Object<T: DriverObject + Send + Sync> { /* private fields */ }

A base GEM object.

Invariants

• self.obj is a valid instance of a struct drm_gem_object.
• self.dev is always a valid pointer to a struct drm_device.

Implementations

impl<T: DriverObject> Object<T>

pub const SIZE: usize

The size of this object’s structure.

pub fn new(dev: &Device<T::Driver>, size: usize) -> Result<ARef<Self>>

Create a new GEM object.

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

Returns the Device that owns this GEM object.

Trait Implementations

impl<T: DriverObject> AllocImpl for Object<T>

const ALLOC_OPS: AllocOps

impl<T: DriverObject> AlwaysRefCounted for Object<T>

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.

fn into_gem_obj(&self) -> &Opaque<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.

fn from_gem_obj(obj: *mut drm_gem_object) -> *mut Self
