This enum describes the type of error that occurred during the parsing of a JSON document.

Constant	Value	Description
`QJsonParseError::NoError`	`0`	No error occurred
`QJsonParseError::UnterminatedObject`	`1`	An object is not correctly terminated with a closing curly bracket
`QJsonParseError::MissingNameSeparator`	`2`	A comma separating different items is missing
`QJsonParseError::UnterminatedArray`	`3`	The array is not correctly terminated with a closing square bracket
`QJsonParseError::MissingValueSeparator`	`4`	A colon separating keys from values inside objects is missing
`QJsonParseError::IllegalValue`	`5`	The value is illegal
`QJsonParseError::TerminationByNumber`	`6`	The input stream ended while parsing a number
`QJsonParseError::IllegalNumber`	`7`	The number is not well formed
`QJsonParseError::IllegalEscapeSequence`	`8`	An illegal escape sequence occurred in the input
`QJsonParseError::IllegalUTF8String`	`9`	An illegal UTF8 sequence occurred in the input
`QJsonParseError::UnterminatedString`	`10`	A string wasn't terminated with a quote
`QJsonParseError::MissingObject`	`11`	An object was expected but couldn't be found
`QJsonParseError::DeepNesting`	`12`	The JSON document is too deeply nested for the parser to parse it
`QJsonParseError::DocumentTooLarge`	`13`	The JSON document is too large for the parser to parse it
`QJsonParseError::GarbageAtEnd`	`14`	The parsed document contains additional garbage characters at the end

Returns the human-readable message appropriate to the reported JSON parsing error.

See also error.

Contains the type of the parse error. Is equal to QJsonParseError::NoError if the document was parsed correctly.

See also ParseError and errorString().

Contains the byte offset in the UTF-8 byte array where the parse error occurred.
