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".
