Defined in:
lib/caution/cause_injecting_error.rb

Overview

This provide some context as to which lower level exception casued the error. Nested exceptions are a relatively new idea to the Ruby ecosystem most things do not print out the entire exception chain. This works around that by injecting the original stack trace into the error message.

Usage:

begin

# Some code which may raise an exception

end rescue

raise CauseInjectingError, 'An helpful message'

end

CauseInjectingError will automatically save the original error using the “cause” functionality of Exception.
