Enum FocusState 

pub enum FocusState {
    Active,
    ActiveParent,
    Captured,
    Inactive,
}

Focus state of a focus target node.

This mirrors Jetpack Compose’s FocusState enum which tracks whether a node is focused, has a focused child, or is inactive.

Variants

Active

The focusable component is currently active (i.e. it receives key events).

ActiveParent

One of the descendants of the focusable component is Active.

Captured

The focusable component is currently active (has focus), and is in a state where it does not want to give up focus. (Eg. a text field with an invalid phone number).

Inactive

The focusable component does not receive any key events. (ie it is not active, nor are any of its descendants active).

Implementations

impl FocusState

pub fn is_focused(self) -> bool

Returns whether the component is focused (Active or Captured).

pub fn has_focus(self) -> bool

Returns whether this node or any descendant has focus.

pub fn is_captured(self) -> bool

Returns whether focus is captured.

Trait Implementations

impl Clone for FocusState

fn clone(&self) -> FocusState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FocusState

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

Formats the value using the given formatter.

impl Default for FocusState

fn default() -> FocusState

Returns the “default value” for a type.

impl Hash for FocusState

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 FocusState

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