Exception: Rooibos::Error::Invariant

Inherits:

Rooibos::Error

• Object
• StandardError
• Rooibos::Error
• Rooibos::Error::Invariant

Defined in:

lib/rooibos/error.rb

Overview

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.
