How to Capture All Errors Returned by a Function Call in Elixir

Elixir, built on Erlang, presents unique challenges and opportunities in error handling compared to mainstream programming languages like Java, C++, and Python. While mainstream languages typically rely on exceptions within a single operating system thread, Elixir and Erlang use a variety of mechanisms, including raised and thrown exceptions, and exit signals, to handle errors in their inherently concurrent and distributed systems. This complexity requires Elixir users to adopt different strategies for error capturing, such as process linking, monitoring, and the use of Task.Supervisor, which allow errors to be managed across multiple processes without affecting the invoking process. The "fail fast" philosophy encourages letting processes terminate and restart from a known state, rather than attempting to fix unexpected errors. The article also introduces the Wormhole module as a production-ready solution for simplifying error capturing in Elixir applications. Elixir's design for fault-tolerant applications emphasizes the need for precise error handling and encourages developers to utilize the language's concurrency features to manage errors effectively.
