#cover_up_backtrace ⇒ Object

Cover up trace for current exception

Examples:

bad case

begin
  call_exceptional_lib!
rescue ExceptionalLib::SomeException => e
  send_alert_to_developer
  raise e # => raised `ExceptionalLib::SomeException` with backtrace started
          #      from current line and not contained origin exception backtrace
          #      that can be very painful for debug
end

resolve

begin
  call_exceptional_lib!
rescue ExceptionalLib::SomeException => e
  send_alert_to_developer
  raise e.cover_up_backtrace # => raised `ExceptionalLib::SomeException` with original backtrace
                             #       so you can easily find out where exception starts
