Struct Registration 

pub struct Registration<'a, T: Operations> { /* private fields */ }

A registered fwctl device.

Owns the RegistrationData made available to driver callbacks. The parent device lifetime ensures that fwctl_unregister runs before the parent driver unbinds.

On drop the device is unregistered (all user contexts are closed and ops is set to NULL) and the registration data is dropped.

Implementations

impl<'a, T: Operations> Registration<'a, T>

pub unsafe fn new( parent: &'a Device<Bound>, dev: &Device<T>, reg_data: impl PinInit<T::RegistrationData<'a>, Error>, ) -> Result<Self>

Register a previously allocated fwctl device with the given registration data.

The reg_data is owned by the registration and accessible during callbacks.

Safety

Callers must not mem::forget() the returned Registration or otherwise prevent its Drop implementation from running, since fwctl_unregister must be called before the parent device is unbound.

dev must be an unregistered Device that is not associated with any live Registration, and no other thread may attempt to register the same device concurrently.

Trait Implementations

impl<T: Operations> Drop for Registration<'_, T>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
