Enum InstallVuiError

        widget: Box<dyn WidgetController>,
        error: Box<InstallVuiError>,

}

Errors that may arise from setting up LayoutTrees and Widgets and installing them in a Space.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

WidgetInitialization

The widget failed to initialize for some reason.

Fields

widget: Box<dyn WidgetController>

TODO: This should be Arc<dyn Widget> instead. Or, if we come up with some way of giving widgets IDs, that.

error: Box<InstallVuiError>

The error returned by WidgetController::initialize().

#[non_exhaustive]

Conflict

A transaction conflict arose between two widgets or parts of a widget’s installation.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

error: SpaceTransactionConflict

OutOfBounds

The widget attempted to modify space outside its assigned bounds.

Fields

grant: LayoutGrant

The region given to the widget.

erroneous: GridAab

The region the widget attempted to modify.

widget: Arc<dyn Widget>

The widget.

#[non_exhaustive]

ExecuteInstallation

Installing the widget tree failed, because one of the widgets’ transactions failed. This usually indicates a bug in the widget implementation.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

error: ExecuteError<SpaceTransaction>

Trait Implementations

impl Debug for InstallVuiError

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

Formats the value using the given formatter.

impl Display for InstallVuiError

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

Formats the value using the given formatter.

impl Error for InstallVuiError

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 From<InstallVuiError> for InGenError

fn from(value: InstallVuiError) -> Self

Converts to this type from the input type.
