/*
|
||||
* QR Code generator test worker (Rust)
|
||||
*
|
||||
* This program reads data and encoding parameters from standard input and writes
|
||||
* QR Code bitmaps to standard output. The I/O format is one integer per line.
|
||||
* Run with no command line arguments. The program is intended for automated
|
||||
* batch testing of end-to-end functionality of this QR Code generator library.
