Struct wayland_server::protocol::wl_seat::WlSeat

pub struct WlSeat(_);

Implementations

impl WlSeat

pub fn capabilities(&self, capabilities: Capability)

seat capabilities changed

This is emitted whenever a seat gains or loses the pointer, keyboard or touch capabilities. The argument is a capability enum containing the complete set of capabilities this seat has.

When the pointer capability is added, a client may create a wl_pointer object using the wl_seat.get_pointer request. This object will receive pointer events until the capability is removed in the future.

When the pointer capability is removed, a client should destroy the wl_pointer objects associated with the seat where the capability was removed, using the wl_pointer.release request. No further pointer events will be received on these objects.

In some compositors, if a seat regains the pointer capability and a client has a previously obtained wl_pointer object of version 4 or less, that object may start sending pointer events again. This behavior is considered a misinterpretation of the intended behavior and must not be relied upon by the client. wl_pointer objects of version 5 or later must not send events if created before the most recent event notifying the client of an added pointer capability.

The above behavior also applies to wl_keyboard and wl_touch with the keyboard and touch capabilities, respectively.

pub fn name(&self, name: String)

unique identifier for this seat

In a multi-seat configuration the seat name can be used by clients to help identify which physical devices the seat represents.

The seat name is a UTF-8 string with no convention defined for its contents. Each name is unique among all wl_seat globals. The name is only guaranteed to be unique for the current compositor instance.

The same seat names are used for all clients. Thus, the name can be shared across processes to refer to a specific wl_seat global.

The name event is sent after binding to the seat global. This event is only sent once per seat object, and the name does not change over the lifetime of the wl_seat global.

Compositors may re-use the same seat name if the wl_seat global is destroyed and re-created later.

Only available since version 2 of the interface.

Trait Implementations

impl AsRef<Resource<WlSeat>> for WlSeat

fn as_ref(&self) -> &Resource<Self>

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for WlSeat

fn clone(&self) -> WlSeat

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WlSeat

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

Formats the value using the given formatter.

impl From<Resource<WlSeat>> for WlSeat

fn from(value: Resource<Self>) -> Self

Converts to this type from the input type.

impl Interface for WlSeat

type Request = Request

Set of requests associated to this interface

type Event = Event

Set of events associated to this interface

const NAME: &'static str = "wl_seat"

Name of this interface

const VERSION: u32 = 7u32

Maximum supported version of this interface

fn c_interface() -> *const wl_interface

impl PartialEq<WlSeat> for WlSeat

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

This method tests for self and other values to be equal, and is used by ==.

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

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