pub struct Registration<const N: usize> { /* private fields */ }
Expand description

Character device registration.

May contain up to a fixed number (N) of devices. Must be pinned.

Implementations

Creates a Registration object for a character device.

This does not register the device: see Self::register().

This associated function is intended to be used when you need to avoid a memory allocation, e.g. when the Registration is a member of a bigger structure inside your crate::Module instance. If you are going to pin the registration right away, call Self::new_pinned() instead.

Creates a pinned Registration object for a character device.

This does not register the device: see Self::register().

Registers a character device.

You may call this once per device type, up to N times.

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
