Enum PlatformFocusedWindow 

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

Backend focused-window signal for multi-viewport focus reconciliation.

Variants

Unavailable

The backend cannot reliably report the focused application window for this snapshot.

NoWindow

The backend reliably reported that no application window is focused.

Window(AnyWindowHandle)

The backend reliably reported the focused application window.

Implementations

impl PlatformFocusedWindow

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

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

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

Returns the focused application window when the backend reported one.

pub fn is_available(self) -> bool

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

Trait Implementations

impl Clone for PlatformFocusedWindow

fn clone(&self) -> PlatformFocusedWindow

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for PlatformFocusedWindow

impl Debug for PlatformFocusedWindow

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

Formats the value using the given formatter.

impl Default for PlatformFocusedWindow

fn default() -> PlatformFocusedWindow

Returns the “default value” for a type.

impl Eq for PlatformFocusedWindow

impl PartialEq for PlatformFocusedWindow

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