intan.io._exceptions

Custom exception classes used throughout the intan package.

These exceptions provide clearer debugging information for: - Invalid or corrupted .rhd files - Mismatched channel definitions - Broken TCP streams from the RHX server - File size or format inconsistencies

Each exception inherits from Exception and includes a brief description.

exception UnrecognizedFileError

Bases: Exception

Exception returned when reading a file as an RHD header yields an invalid magic number (indicating this is not an RHD header file).

exception UnknownChannelTypeError
