Exceptions
**********

Public exception hierarchy for pyStrich.

Added in version 0.11: Unified exception hierarchy. All pyStrich-
raised errors now inherit from "PyStrichError"; all pyStrich-emitted
warnings inherit from "PyStrichWarning".

exception PyStrichError

   Bases: "Exception"

   Base class for all pyStrich-specific errors.

   Added in version 0.11.

exception PyStrichInvalidInput

   Bases: "PyStrichError"

   The text being encoded is not valid for the chosen barcode format.

   Typically raised in response to end-user-supplied input.

   Added in version 0.11.

exception PyStrichInvalidOption

   Bases: "PyStrichError"

   An encoder option (configuration argument) is invalid.

   Typically a programmer error: options are usually hardcoded by the
   caller rather than passed through from end-user input.

   Added in version 0.11.

exception PyStrichWarning

   Bases: "UserWarning"

   Base class for pyStrich-specific warnings.

   Added in version 0.11.

exception Fnc1WorkaroundCompatWarning

   Bases: "PyStrichWarning"

   The legacy chr(231) FNC1 trick triggered the compat shim; use the
   FNC1 constant instead.

   Added in version 0.11.

exception DataMatrixNonAsciiWarning

   Bases: "PyStrichWarning"

   DataMatrix input contains non-ASCII characters; output will not
   decode correctly.

   Added in version 0.11.
