Trait DriverObject 

pub trait DriverObject:
    Sync
    + Send
    + Sized {
    type Driver: Driver;
    type Args;

    // Required method
    fn new<Ctx: DeviceContext>(
        dev: &Device<Self::Driver, Ctx>,
        size: usize,
        args: Self::Args,
    ) -> impl PinInit<Self, Error>;

    // Provided methods
    fn open(_obj: &DriverAllocImpl<Self>, _file: &DriverFile<Self>) -> Result { ... }
    fn close(_obj: &DriverAllocImpl<Self>, _file: &DriverFile<Self>) { ... }
}

GEM object functions, which must be implemented by drivers.

Required Associated Types

type Driver: Driver

Parent Driver for this object.

type Args

The data type to use for passing arguments to DriverObject::new.

Required Methods

fn new<Ctx: DeviceContext>( dev: &Device<Self::Driver, Ctx>, size: usize, args: Self::Args, ) -> impl PinInit<Self, Error>

Create a new driver data object for a GEM object of a given size.

Provided Methods

fn open(_obj: &DriverAllocImpl<Self>, _file: &DriverFile<Self>) -> Result

Open a new handle to an existing object, associated with a File.

fn close(_obj: &DriverAllocImpl<Self>, _file: &DriverFile<Self>)

Close a handle to an existing object, associated with a File.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
