Expand description

Base operations shared by all GEM object classes

Provided Methods§

Source

fn size(&self) -> usize

Returns the size of the object in bytes.

Source

fn create_handle<D, F>(&self, file: &File<F>) -> Result<u32>
where Self: AllocImpl<Driver = D>, D: Driver<Object = Self, File = F>, F: DriverFile<Driver = D>,

Creates a new handle for the object associated with a given File (or returns an existing one).

Source

fn lookup_handle<D, F>(file: &File<F>, handle: u32) -> Result<ARef<Self>>
where Self: AllocImpl<Driver = D>, D: Driver<Object = Self, File = F>, F: DriverFile<Driver = D>,

Looks up an object by its handle for a given File.

Source

fn create_mmap_offset(&self) -> Result<u64>

Creates an mmap offset to map the object from userspace.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
