Struct Pointer 

pub struct Pointer(/* private fields */);

Device sub-interface for relative pointer motion.

Server-side interface proxy for interface ei_pointer.

Interface for relative pointer motion requests and events.

This interface is only provided once per device and where a client requests ei_pointer.release the interface does not get re-initialized. An EIS implementation may adjust the behavior of the device (including removing the device) if the interface is released.

Implementations

impl Pointer

pub fn version(&self) -> u32

Returns the negotiated version of the interface.

pub fn is_alive(&self) -> bool

Returns true if the backend has this object.

impl Pointer

pub fn destroyed(&self, serial: u32)

Pointer removal notification.

Note: This event is a destructor.

This object has been removed and a client should release all associated resources.

This object will be destroyed by the EIS implementation immediately after after this event is sent and as such the client must not attempt to use it after that point.

Parameters

• serial: This event’s serial number.

pub fn motion_relative(&self, x: f32, y: f32)

Relative motion event.

Note: This event may only be used in a receiver context type.

See the ei_pointer.motion_relative request for details.

It is a protocol violation to send this request for a client of an ei_handshake.context_type other than receiver.

Parameters

• x
• y

Trait Implementations

impl Clone for Pointer

fn clone(&self) -> Pointer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Pointer

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for Pointer

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Interface for Pointer

const NAME: &'static str = "ei_pointer"

The name of the interface like ei_device.

const VERSION: u32 = 1

The version of the interface this interface proxy supports.

const CLIENT_SIDE: bool = false

Whether this interface proxy is to be used on the client or the server side.

fn new_unchecked(object: Object) -> Self

Returns an interface proxy without checking Object::interface.

fn as_object(&self) -> &Object

Returns a reference to the object contained in the interface proxy.

fn as_arg(&self) -> Arg<'_>

Returns an Arg to reference this object in events or requests.

impl PartialEq for Pointer

fn eq(&self, other: &Pointer) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
