Enum WindowUnderCursorSource 

pub enum WindowUnderCursorSource {
    Unknown,
    PlatformWin32,
    PlatformMacos,
    Latched,
    HeuristicZOrder,
    HeuristicRects,
}

Best-effort diagnostics hint: which mechanism was used to select the hovered window during a cross-window drag session.

This is primarily intended for multi-window docking diagnostics (“hovered window under cursor” selection under overlap), so bundles can answer whether the runner used an OS-backed path or a heuristic fallback.

Variants

Unknown

No source information is available (or the runner has not attempted selection yet).

PlatformWin32

OS-backed Win32 window-under-cursor selection (z-order traversal).

PlatformMacos

OS-backed macOS window-under-cursor selection.

Latched

Stable latch (reuse the previously hovered window while the cursor remains inside it).

HeuristicZOrder

Runner-maintained z-order list / rect scan (best-effort heuristic).

HeuristicRects

Full window-rect scan (best-effort heuristic).

Trait Implementations

impl Clone for WindowUnderCursorSource

fn clone(&self) -> WindowUnderCursorSource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WindowUnderCursorSource

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

Formats the value using the given formatter.

impl Default for WindowUnderCursorSource

fn default() -> WindowUnderCursorSource

Returns the “default value” for a type.

impl Hash for WindowUnderCursorSource

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 PartialEq for WindowUnderCursorSource

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