Struct DataBarEncoder 

pub struct DataBarEncoder;

GS1 DataBar encoder.

Implementations

impl DataBarEncoder

pub fn new() -> Self

A new encoder.

pub fn build_omni(&self, gtin: &[u8]) -> Result<Symbol>

Build a GS1 DataBar Omnidirectional symbol from a GTIN (13 or 14 digits).

A 13-digit body has its GS1 check digit appended; a 14-digit GTIN is validated against its check digit. The stored symbol carries the canonical 14-digit GTIN as a single numeric segment.

pub fn build_limited(&self, gtin: &[u8]) -> Result<Symbol>

Build a GS1 DataBar Limited symbol from a GTIN (13 or 14 digits).

Limited only encodes GTINs whose indicator (leading) digit is 0 or 1.

pub fn build_stacked(&self, gtin: &[u8]) -> Result<Symbol>

Build a GS1 DataBar Stacked symbol (the two-row form of DataBar-14) from a GTIN (13 or 14 digits). The payload is the canonical 14-digit GTIN.

pub fn build_stacked_omni(&self, gtin: &[u8]) -> Result<Symbol>

Build a GS1 DataBar Stacked Omnidirectional symbol from a GTIN (13 or 14 digits). The payload is the canonical 14-digit GTIN.

pub fn build_expanded_stacked( &self, gs1: &[u8], columns_per_row: usize, ) -> Result<Symbol>

Build a GS1 DataBar Expanded Stacked symbol from a reduced GS1 element string, placing columns_per_row column pairs (codeblocks) on each stacked row.

columns_per_row must be in 1..=11 (ISO/IEC 24724:2011 §7.2.8); the common default is 2. See DataBarEncoder::build_expanded for the payload format.

pub fn build_expanded(&self, gs1: &[u8]) -> Result<Symbol>

Build a GS1 DataBar Expanded symbol from a reduced GS1 element string.

gs1 is the Application Identifier data in reduced form: AI numbers and their values concatenated, with a GS1 separator (FNC1, byte 0x1D) after a variable-length AI’s value when another AI follows. The bytes are validated by running the encodation and stored verbatim as a single Segment::byte.
