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.

Bases: UserWarning

Base class for pyStrich-specific warnings.

Added in version 0.11.
