}
Expand description
QrError
encodes the error encountered when generating a QR code.
Variants
DataTooLong
The data is too long to encode into a QR code for the given version.
InvalidVersion
The provided version / error correction level combination is invalid.
UnsupportedCharacterSet
Some characters in the data cannot be supported by the provided QR code version.
InvalidEciDesignator
The provided ECI designator is invalid. A valid designator should be between 0 and 999999.
InvalidCharacter
A character not belonging to the character set is found.
