## 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 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.

### QCborError::operator QCborError::Code() const

Returns the error code that this QCborError object stores.
