Module codes 

Per-symbology implementations. Each submodule provides encode/decode (and later detection) for one symbology family. Only qr is implemented so far; the other modules are pre-declared stubs whose encode/decode return crate::Error::Unsupported until filled in. Query crate::Symbology::is_implemented for current coverage.

Modules

aztec

Aztec Code (ISO/IEC 24778) encoder and structural decoder.

codabar

Codabar (a.k.a. NW-7, USD-4, Code 2 of 7).

codablockf

Codablock F (AIM ISS-X-24): a stacked Code 128 symbology. Each row is a Code 128 line carrying row-count/row-number indicator columns; the whole symbol is protected by the K1/K2 data check characters.

code11

Code 11 (USD-8) encoder and structural decoder.

code39

Code 39 (ISO/IEC 16388) encoder and structural decoder.

code49

Code 49 (ANSI/AIM BC6-2000): a stacked alphanumeric symbology of 2 to 8 rows, each row holding four 16-module symbol characters that pack seven base-49 codewords plus a per-row check character.

code93

Code 93 encoder and structural decoder.

code16k

Code 16K (BS EN 12323:2005): a stacked symbology built on the Code 128 character set, holding 2 to 16 rows of five symbol characters each.

code128

Code 128 (ISO/IEC 15417) and GS1-128 encoder and structural decoder.

databar

GS1 DataBar (formerly RSS) linear symbologies.
