Struct ExtImageCopyCaptureCursorSessionV1

pub struct ExtImageCopyCaptureCursorSessionV1 { /* private fields */ }

Available on crate feature wayland and Linux only.

cursor capture session

This object represents a cursor capture session. It extends the base capture session with cursor-specific metadata.

See also the Event enum for this interface.

Implementations

impl ExtImageCopyCaptureCursorSessionV1

pub fn destroy(&self)

delete this object

Destroys the session. This request can be sent at any time by the client.

This request doesn’t affect ext_image_copy_capture_frame_v1 objects created by this object.

pub fn get_capture_session<U, D>( &self, qh: &QueueHandle<D>, udata: U, ) -> ExtImageCopyCaptureSessionV1

where U: Send + Sync + 'static, D: Dispatch<ExtImageCopyCaptureSessionV1, U> + 'static,

get image copy capturer session

Gets the image copy capture session for this cursor session.

The session will produce frames of the cursor image. The compositor may pause the session when the cursor leaves the captured area.

This request must not be sent more than once, or else the duplicate_session protocol error is raised.

impl PartialEq<Weak<ExtImageCopyCaptureCursorSessionV1>> for ExtImageCopyCaptureCursorSessionV1

fn eq(&self, other: &Weak<ExtImageCopyCaptureCursorSessionV1>) -> 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.
