Implementations

impl InputDevice

pub fn new_touch( display_width: i32, display_height: i32, info: InputDeviceInfoHandle, node_name: &str, inspect_node: &Node, ) -> Self

pub fn new_keyboard( info: InputDeviceInfoHandle, node_name: &str, inspect_node: &Node, ) -> Self

pub fn new_mouse( info: InputDeviceInfoHandle, node_name: &str, inspect_node: &Node, ) -> Self

pub fn register(self, kernel: &Kernel, minor: u32) -> Result<Device, Errno>

Registers the input device, and its event interface, with the kernel’s device registry.

Linux exposes each input device as an inputN device of the input class, with the eventN character device for its event interface nested beneath it, e.g.:

/sys/devices/virtual/input/input0/
├── name
├── uevent
├── id/{bustype,vendor,product,version}
└── event0/
    ├── dev
    └── uevent

Since both devices belong to the input class, event{minor} is created directly within the input{minor} directory, without an intermediate class directory. Each is also linked from /sys/class/input.

Only the eventN device generates a uevent, since it is the only device with a /dev node.

Returns the eventN Device, which should be passed to Self::unregister to remove both devices.

pub fn unregister(current_task: &CurrentTask, event_device: Device)

Unregisters an input device previously registered with Self::register.

event_device is the eventN Device returned by Self::register; its parent inputN device is removed too.

pub fn open_internal(&self) -> Box<dyn FileOps>

Trait Implementations

impl Clone for InputDevice

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl DeviceOps for InputDevice

fn open( &self, _current_task: &CurrentTask, _id: StarnixDeviceId, _node: &NamespaceNode, _flags: OpenFlags, ) -> Result<Box<dyn FileOps>, Errno>
