Ruby provides a hierarchy of built-in classes to simplify exception handling. In fact, the exception names that you see when your program crashes, such as TypeError, are actually class names. The class at the very top of the hierarchy is the Exception class. Exception has several subclasses, many of which have descendents of their own.

At the top-most level of the exception class hierarchy resides the Exception class, the monolithic parent class of over a half-dozen subclasses that typically regulate the grunt work of Ruby exception handling. 2018-04-10 · When rescuing an exception in Ruby, you can specify a specific error class that should be rescued from. 1 2 3 4 5. begin raise 'This exception will be rescued!' rescue StandardError => e puts "Rescued: # {e.inspect}" end.
