Struct kernel::miscdevice::MiscDeviceRegistration

pub struct MiscDeviceRegistration<T> { /* private fields */ }

A registration of a miscdevice.

Invariants

• inner contains a struct miscdevice that is registered using misc_register().
• This registration remains valid for the entire lifetime of the MiscDeviceRegistration instance.
• Deregistration occurs exactly once in Drop via misc_deregister().
• inner wraps a valid, pinned miscdevice created using MiscDeviceOptions::into_raw.

Implementations

impl<T> MiscDeviceRegistration<T>

pub fn project<'__pin>( self: Pin<&'__pin mut Self> ) -> MiscDeviceRegistrationProjection<'__pin, T>

Pin-projects all fields of Self.

These fields are structurally pinned:

• inner

These fields are not structurally pinned:

• _t

impl<T: MiscDevice> MiscDeviceRegistration<T>

pub fn register(opts: MiscDeviceOptions) -> impl PinInit<Self, Error>

Register a misc device.

pub fn as_raw(&self) -> *mut miscdevice

Returns a raw pointer to the misc device.

pub fn device(&self) -> &Device

Access the this_device field.
