Enum FocusDirection 

pub enum FocusDirection {
    Forward,
    Backward,
}

Direction passed to a SceneView::focus_order callback when the app wants to override the default Tab cycle.

Forward corresponds to Tab; Backward to Shift+Tab. The default SceneView focus traversal is scene insertion order — apps that need data-flow order (graph editor), story-order (corkboard with Acts), chronological order (timeline), etc. install a callback that receives the current focus and returns the next id.

Variants

Forward

Advance to the next item — corresponds to the Tab key.

Backward

Retreat to the previous item — corresponds to Shift+Tab.

Trait Implementations

impl Clone for FocusDirection

fn clone(&self) -> FocusDirection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for FocusDirection

impl Debug for FocusDirection

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

impl Eq for FocusDirection

impl PartialEq for FocusDirection

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