A value in a barcode, consists of regular characters, digits for Code C, and control codes.

Variants

RegularCharacter(char)

A regular character, also includes control characters.

Digit(u8)

A Code C digit, the numbers 0 through 9 are actually 00 through 09.

FNC1

Used to indicate a GS1-128 barcode

FNC2

Indicates that the currently scanned string should be prepended to the next scan

FNC3

Initialize, used for programming scanners

FNC4

Used for extended ASCII support.

StartA

The code used to signal we start in variant A

StartB

The code used to signal we start in variant B

StartC

The code used to signal we start in variant C

Stop

Not actually the stop code, just the one used at the end.

ShiftA

Use variant A for the next character

ShiftB

Use variant B for the next character

CodeA

Switch to variant A from here on out

CodeB

Switch to variant B from here on out

CodeC

Switch to variant C from here on out

Trait Implementations

impl Clone for BarcodeValue

fn clone(&self) -> BarcodeValue

Returns a duplicate of the value.

const fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BarcodeValue

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<char> for BarcodeValue

fn from(value: char) -> Self

Converts to this type from the input type.

impl From<u8> for BarcodeValue

fn from(value: u8) -> Self

Converts to this type from the input type.

impl PartialEq for BarcodeValue

fn eq(&self, other: &BarcodeValue) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
