Enum UPCError

pub enum UPCError {
    UPCOverflow,
    CheckDigitOverflow,
}

Error enum for the UPCs. This is responsable for the Error return on the Result<T, E> E (error) on the UPC.check_upc() method and commonly implaments errors when users use standards implamented by the UPCStandard wrongly.

Error Types

• UPCOverflow: When the i8 array implamented in the standards defined by the UPCStandard enum has been overflown with data that is not 0-9 (1 digit)
• CheckDigitOverflow: When the i8 check_digit value implamented in the UPC has been overflown with data that is not 0-9 (1 digit)
