class Rooibos::Error::Invariant

Invariant violation.

The library enforces rules about valid states and contracts. Breaking these rules raises this error.

Common causes:

• Providing conflicting API parameters (e.g., both fragment and model/view/update)

• Callable return type mismatch (e.g., view returns nil instead of a widget)

To resolve, check the method’s documented contract. Ensure state preconditions are met and return types are correct.

Example

Rooibos.run(model: Model.new, view: nil, update: Update)  # => raises Error::Invariant
