Struct LinearPattern 

pub struct LinearPattern {
    pub bars: Vec<u8>,
    pub text: Option<String>,
}

A 1D bar pattern as a run-length encoding.

bars[i] is the width (in modules) of the i-th element. Even indices (0, 2, 4, …) are bars (foreground), odd indices are spaces (background). This matches BWIPP’s sbs (start-bar-space) convention.

Fields

bars: Vec<u8>

Run-length widths, starting with a bar.

text: Option<String>

Human-readable text rendered beneath the bars (if the symbology supports it).

Implementations

impl LinearPattern

pub fn from_modules(modules: &str, text: Option<String>) -> Self

Build a LinearPattern from a string of ‘1’ and ‘0’ characters where ‘1’ is a bar module and ‘0’ is a space module.

pub fn total_width(&self) -> u32

Total width in modules (sum of all bar/space widths).
