Enum qr2term::QrError

pub enum QrError {
    DataTooLong,
    InvalidVersion,
    UnsupportedCharacterSet,
    InvalidEciDesignator,
    InvalidCharacter,
}

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.
