pub struct Registration<T: Operations> { /* private fields */ }
Expand description

A registration of a miscellaneous device.

Invariants

Context is always initialised when registered is true, and not initialised otherwise.

Implementations

Creates a new Registration but does not register it yet.

It is allowed to move.

Registers a miscellaneous device.

Returns a pinned heap-allocated representation of the registration.

Registers a miscellaneous device with the rest of the kernel.

It must be pinned because the memory block that represents the registration is self-referential.

Registers a miscellaneous device with the rest of the kernel. Additional optional settings are provided via the opts parameter.

It must be pinned because the memory block that represents the registration is self-referential.

Trait Implementations

Returns the “default value” for a type. Read more

Removes the registration from the kernel if it has completed successfully before.

Converts untyped data stored in [struct inode] and [struct file] (when [struct file_operations::open] is called) into the given type. For example, for miscdev devices, a pointer to the registered [struct miscdev] is stored in [struct file::private_data]. Read more
