module SystemError
Overview
This module can be included in any Exception
subclass that is
used to wrap some system error (Errno
or WinError
)
When included it provides a from_errno
method (and from_winerror
on Windows)
to create exception instances with a description of the original error. It also
adds an #os_error
property that contains the original system error.
For example:
class MyError < Exception
include SystemError
end
MyError.from_errno("Something happened")
