Module: Tinymon::Integrations

Defined in:
lib/tinymon/integrations.rb

Overview

Capture unhandled exceptions at process exit. Ruby doesn’t have a true global “uncaught exception” hook the way Python (sys.excepthook) or Java (Thread.setDefaultUncaughtExceptionHandler) do — the closest equivalent is checking $! inside an at_exit block, which fires after a fatal exception has propagated out of ‘main`.
