Exception: RatatuiRuby::Error::Invariant

Inherits:

RatatuiRuby::Error

• Object
• StandardError
• RatatuiRuby::Error
• RatatuiRuby::Error::Invariant

Defined in:

lib/ratatui_ruby.rb

Overview

Invariant violation.

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

Common causes:

• Calling methods in the wrong order (e.g., init_terminal twice)

• 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.
