target: WidgetId

Focusable widget.

DirectOrExit

Move focus to the widget if it is focusable or to the first focusable ancestor.

Fields

target: WidgetId

Maybe focusable widget.

navigation_origin: bool

If true the target becomes the navigation_origin when the first focusable ancestor is focused because the target is not focusable.

DirectOrEnter

Move focus to the widget if it is focusable or to first focusable descendant.

Fields

target: WidgetId

Maybe focusable widget.

navigation_origin: bool

Trait Implementations

impl Clone for FocusTarget

fn clone(&self) -> FocusTarget

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FocusTarget

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FocusTarget

fn deserialize<__D>( __deserializer: __D, ) -> Result<FocusTarget, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for FocusTarget

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