Polymorphic return values are really useful. Often, we just want to know if
|
||
|
|
something worked or not. Other times, we'd like to know what the error text
|
||
|
|
was. Still others, we may want to know what the error code was, and what the
|
||
|
|
error properties were. We don't want to handle objects or data structures for
|
||
|
|
every single return value, but we do want to check error conditions in our
|
||
|
|
code because that's what good programmers do.
|
||
|
|
|
||
|
|
When functions are successful they may return true, or perhaps some useful
|
||
|
|
data. In the quest to provide consistent return values, this gets confusing
|
||
|
|
between complex, informational errors and successful return values.
|
||
|
|
|
||
|
|
This module provides these features with a simple API that should get you what
|
||
|
|
you're looking for in each contex a return value is used in.
