Enum TabNavigationError 

pub enum TabNavigationError {
    NoTabGroups,
    NoFocusableEntities,
    FailedToNavigateToNextFocusableEntity,
    NoTabGroupForCurrentFocus {
        previous_focus: Entity,
        new_focus: Entity,
    },
}

An error that can occur during tab navigation.

Variants

NoTabGroups

No tab groups were found.

NoFocusableEntities

No focusable entities were found.

FailedToNavigateToNextFocusableEntity

Could not navigate to the next focusable entity.

This can occur if your tab groups are malformed.

NoTabGroupForCurrentFocus

No tab group for the current focus entity was found.

Fields

previous_focus: Entity

The entity that was previously focused, and is missing its tab group.

new_focus: Entity

The new entity that will be focused.

If you want to recover from this error, set InputFocus to this entity.

Trait Implementations

impl Clone for TabNavigationError

fn clone(&self) -> TabNavigationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TabNavigationError

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

Formats the value using the given formatter.

impl Display for TabNavigationError

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

Formats the value using the given formatter.

impl Error for TabNavigationError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for TabNavigationError

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