Base operations shared by all GEM object classes

Provided Methods

fn size(&self) -> usize

Returns the size of the object in bytes.

fn create_handle( &self, file: &File<<<Self as IntoGEMObject>::Driver as Driver>::File>, ) -> Result<u32>

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

fn lookup_handle( file: &File<<<Self as IntoGEMObject>::Driver as Driver>::File>, handle: u32, ) -> Result<ARef<Self>>

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

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.
