Enum agui_core::widget::BuildResult

#[non_exhaustive]
pub enum BuildResult {
    Empty,
    One(WidgetRef),
    Many(Vec<WidgetRef>),
    Error(Box<dyn Error>),
}

Encapsulates the result of a widget build() method.

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.

Empty

Indicates that the widget has no children.

One(WidgetRef)

Tuple Fields

0: WidgetRef

The widget contains a single child.

Many(Vec<WidgetRef>)

Tuple Fields

0: Vec<WidgetRef>

The widget contains a many children.

Error(Box<dyn Error>)

Tuple Fields

0: Box<dyn Error>

The widget has failed to build properly, and should construction should halt.

Panics

Currently this results in a panic!(), however that may change in the future.

Implementations
