Enum PointerOwner 

pub enum PointerOwner {
    Window,
    Desktop,
    OtherSurface,
}

Which layer paints a peer’s pointer — a screen position, so only one layer may place it correctly (an app painting a desktop coordinate into its own window space is right only at the origin). The compositor owns desktop-scoped pointers, since it alone spans the strip, chrome and gaps between windows continuously; an app owns presence inside its own content (caret, selection, typing swipe), since the compositor has no access to the text.

Variants

Window

No desktop scope, so no compositor overlay claims it: the SDK/relay dialect, shot fixtures, and the hosted backend’s interpolated cursors.

Desktop

The compositor overlay paints it, from PresenceCtx::pointers. Still kept here so “follow that peer” can read it via PresenceCtx::peer_pointer.

OtherSurface

In some other surface’s content coordinates — the frame arrived (the broker fans presence to every app in the room) but is not this process’s to place. Makes the fan-out safe: exactly one of N apps answers “mine”, the rest land here without consulting each other.

Trait Implementations

impl Clone for PointerOwner

fn clone(&self) -> PointerOwner

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PointerOwner

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

Formats the value using the given formatter.

impl Default for PointerOwner

fn default() -> PointerOwner

Returns the “default value” for a type.

impl PartialEq for PointerOwner

fn eq(&self, other: &PointerOwner) -> 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.

impl Copy for PointerOwner

impl Eq for PointerOwner

impl StructuralPartialEq for PointerOwner
