Exception: StandardError

Inherits:

Exception

• Object
• Exception
• StandardError

Defined in:

error.c,
error.c

Overview

The most standard error types are subclasses of StandardError. A rescue clause without an explicit Exception class will rescue all StandardErrors (and only those).

def foo
  raise "Oups"
end
foo rescue "Hello"   #=> "Hello"

On the other hand:

require 'does/not/exist' rescue "Hi"

raises the exception:

LoadError: no such file to load -- does/not/exist

Direct Known Subclasses
