Enum PlatformHoveredWindow 

pub enum PlatformHoveredWindow {
    Unavailable,
    NoWindow,
    Window(AnyWindowHandle),
}

Backend hovered-window signal for multi-viewport routing.

Variants

Unavailable

The backend cannot reliably report the window under the pointer for this snapshot.

NoWindow

The backend reliably reported that no application window is under the pointer.

Window(AnyWindowHandle)

The backend reliably reported the application window under the pointer.

Implementations

impl PlatformHoveredWindow

pub fn from_window(window: Option<AnyWindowHandle>) -> Self

Converts a reliable optional window into a hovered-window signal.

pub fn window(self) -> Option<AnyWindowHandle>

Returns the hovered application window when the backend reported one.

pub fn is_available(self) -> bool

Returns true when the backend can distinguish no hovered application window from unknown.

Trait Implementations

impl Eq for PlatformHoveredWindow

impl PartialEq for PlatformHoveredWindow

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