Error variants regarding structured append

Variants§

AtLeast2Pieces

Structured append mode should contain at least two qrcodes

TotalMismatch(usize)

Encoded number of pieces does not match real number of pieces

MissingParts

Not all the QR codes parts are present

Parity

Computed parity byte does not match

TooShort

QR code data shorter than 5 bytes

StructuredWrongMode

QR code mode is not structured append

StructuredWrongEnc

QR code encoding is not the one supported in structured append

SeqGreaterThanTotal(u8, u8)

QR code sequence number is greater than total

LengthMismatch(usize, usize)

QR code length mismatch

UnsupportedVersion(i16)

Unsupported version

SplitMax16(usize)

Maximum supported pieces in structured append is 16
