Crate barcodes 

barcodes

A universal bar/QR code generation library supporting many symbologies.

Zero-allocation core

By default the crate is pure no_std and performs no heap allocation. Encoders write their module data into a caller-provided &mut [bool] buffer via BarcodeEncoder::encode_into.

Enable the optional alloc feature for the convenience BarcodeEncoder::encode method (returns an owned BarcodeOutput) and SVG string rendering. The image feature (implies std) adds raster output.

Modules

• common — shared traits, types, errors, and output helpers
• qrcode — QR Code Model 2 encoder
• ean_upc — EAN-13, EAN-8, UPC-A, UPC-E encoders
• linear — Code 128, Code 39, Code 93, Codabar, ITF encoders
• gs1 — GS1-128 and GS1 DataBar encoders
• twod — PDF417, Data Matrix, Aztec Code encoders
• postal — USPS IMb and Royal Mail RM4SCC encoders
