Module optimize 

Data mode segmentation optimizer.

QR codes support four data modes (Numeric, Alphanumeric, Byte, Kanji), each with different efficiency for different character types. This module finds the optimal sequence of mode switches to minimize the total number of bits required to encode the input data.

The optimizer uses dynamic programming to explore all possible mode transitions and selects the segmentation that produces the shortest bit stream for the target QR code version.

Structs

Optimizer

Iterator that merges consecutive parser segments to minimize the total encoded length for a given Version. Created via Parser::optimize.

Parser

QR code data parser to classify the input into distinct segments.

Segment

A segment of data committed to an encoding mode.

Functions

optimize_segments

Computes the minimum-size merge plan for parser segments.

total_encoded_len

Computes the total encoded length of all segments.
