Trait kernel::driver::DriverLayout

pub unsafe trait DriverLayout {
    type DriverType: Default;
    type DriverData;

    const DEVICE_DRIVER_OFFSET: usize;
}

Trait describing the layout of a specific device driver.

This trait describes the layout of a specific driver structure, such as struct pci_driver or struct platform_driver.

Safety

Implementors must guarantee that:

• DriverType is repr(C),
• DriverData is the type of the driver’s device private data.
• DriverType embeds a valid struct device_driver at byte offset DEVICE_DRIVER_OFFSET.

Required Associated Types

type DriverType: Default

The specific driver type embedding a struct device_driver.

type DriverData

The type of the driver’s device private data.

Required Associated Constants

const DEVICE_DRIVER_OFFSET: usize

Byte offset of the embedded struct device_driver within DriverType.

This must correspond exactly to the location of the embedded struct device_driver field.

Object Safety

This trait is not object safe.
