data ASN1Length Source
ASN1 Length with all different formats
Constructors
| LenShort Int | Short form with only one byte. length has to be < 127. |
| LenLong Int Int | Long form of N bytes |
| LenIndefinite | Length is indefinite expect an EOC in the stream to finish the type |

| StreamConstructionWrongSize | A construction goes over the size specified in the header. |
| StreamUnexpectedSituation String | An unexpected situation has come up parsing an ASN1 event stream. |
| ParsingHeaderFail String | Parsing an invalid header. |
| ParsingPartial | Parsing is not finished, there is construction unended. |
| TypeNotImplemented String | Decoding of a type that is not implemented. Contribution welcome. |
| TypeDecodingFailed String | Decoding of a knowed type failed. |
| PolicyFailed String String | Policy failed including the name of the policy and the reason. |
