Inherits:

Defined in:
lib/typed_operation/chains/fallback_chain.rb

Overview

Fallback chain created by .or_else Calls the fallback only when the left operation fails. Passes through success unchanged.

For blocks: passes the failure value. For operations: passes the original call arguments (so fallback can retry).
