QCborError Struct
The QCborError class holds the error condition found while parsing or validating a CBOR stream. More...

This struct was introduced in Qt 5.12.
Note: All functions in this struct are reentrant.

Member Type Documentation
enum QCborError::Code
This enum contains the possible error condition codes.
| Constant | Value | Description |
|---|---|---|
QCborError::NoError | 0 | No error was detected. |
QCborError::UnknownError | 1 | An unknown error occurred and no further details are available. |
QCborError::AdvancePastEnd | 3 | QCborStreamReader::next() was called but there are no more elements in the current context. |
QCborError::InputOutputError | 4 | An I/O error with the QIODevice occurred. |
QCborError::GarbageAtEnd | 256 | Data was found in the input stream after the last element. |
QCborError::EndOfFile | 257 | The end of the input stream was unexpectedly reached while processing an element. |
QCborError::UnexpectedBreak | 258 | The CBOR stream contains a Break where it is not allowed (data is corrupt and the error is not recoverable). |
QCborError::UnknownType | 259 | The CBOR stream contains an unknown/unparsable Type (data is corrupt and the and the error is not recoverable). |
QCborError::IllegalType | 260 | The CBOR stream contains a known type in a position it is not allowed to exist (data is corrupt and the error is not recoverable). |
QCborError::IllegalNumber | 261 | The CBOR stream appears to be encoding a number larger than 64-bit (data is corrupt and the error is not recoverable). |
QCborError::IllegalSimpleType | 262 | The CBOR stream contains a Simple Type encoded incorrectly (data is corrupt and the error is not recoverable). |
QCborError::InvalidUtf8String | 516 | The CBOR stream contains a text string that does not decode properly as UTF-8 (data is corrupt and the error is not recoverable). |
QCborError::DataTooLarge | 1024 | CBOR string, map or array is too big and cannot be parsed by Qt (internal limitation, but the error is not recoverable). |
QCborError::NestingTooDeep | 1025 | Too many levels of arrays or maps encountered while processing the input (internal limitation, but the error is not recoverable). |
QCborError::UnsupportedType | 1026 | The CBOR stream contains a known type that the implementation does not support (internal limitation, but the error is not recoverable). |
Member Function Documentation
QString QCborError::toString() const
Returns a text string that matches the error code in this QCborError object.
Note: the string is not translated. Applications whose interface allow users to parse CBOR streams need to provide their own, translated strings.
See also QCborError::Code.
Code QCborError::operator Code() const
Returns the error code that this QCborError object stores.
