Exceptions

pychilaslasers.exceptions

PyChilasLasers exceptions module.

This module contains all custom exceptions for the PyChilasLasers library. These exceptions provide specific error handling for laser operations and modes.

Authors: SDU

Modules:

  • laser_error –

    Class representing errors received from the laser.

  • mode_error –

    Exception class for laser mode-related errors.

Classes:

LaserError(code: str, message: str)

Bases: Exception

Parameters:

  • code (str) –

    The error code sent by the laser. Typically a 1 but kept abstract to allow for future expansion.

  • message (str) –

    The error message.

ModeError(message: str, current_mode: LaserMode | Mode, desired_mode: LaserMode | Mode | None = None)

Bases: Exception

Exception raised for errors related to the laser mode.

This exception is used to indicate that an operation cannot be performed in the current mode of the laser. It provides information about the current mode and the desired mode that would allow the operation to succeed

Parameters:

  • message (str) –

    The error message.

  • current_mode (LaserMode) –

    The current mode of the laser.

  • desired_mode (LaserMode | None, default: None ) –

    The laser mode that would allow for the operation to succeed. Defaults to None.
