PyAsn1Error¶

class pyasn1.error.PyAsn1Error(*args, **kwargs)¶

Base pyasn1 exception

PyAsn1Error is the base exception class (based on Exception) that represents all possible ASN.1 related errors.

property context¶

Return exception context

When exception object is created, the caller can supply some opaque context for the upper layers to better understand the cause of the exception.

ValueConstraintError¶

class pyasn1.error.ValueConstraintError(*args, **kwargs)¶

ASN.1 type constraints violation exception

The ValueConstraintError exception indicates an ASN.1 value constraint violation.

It might happen on value object instantiation (for scalar types) or on serialization (for constructed types).

class pyasn1.error.SubstrateUnderrunError(*args, **kwargs)¶

ASN.1 data structure deserialization error

The SubstrateUnderrunError exception indicates insufficient serialised data on input of a de-serialization codec.

class pyasn1.error.PyAsn1UnicodeError(message, unicode_error=None)¶

Unicode text processing error

The PyAsn1UnicodeError exception is a base class for errors relating to unicode text de/serialization.

Apart from inheriting from PyAsn1Error, it also inherits from UnicodeError to help the caller catching unicode-related errors.

class pyasn1.error.PyAsn1UnicodeDecodeError(message, unicode_error=None)¶

Unicode text decoding error

The PyAsn1UnicodeDecodeError exception represents a failure to deserialize unicode text.

Apart from inheriting from PyAsn1UnicodeError, it also inherits from UnicodeDecodeError to help the caller catching unicode-related errors.

class pyasn1.error.PyAsn1UnicodeEncodeError(message, unicode_error=None)¶

Unicode text encoding error

The PyAsn1UnicodeEncodeError exception represents a failure to serialize unicode text.

Apart from inheriting from PyAsn1UnicodeError, it also inherits from UnicodeEncodeError to help the caller catching unicode-related errors.
