Struct StackedPattern 

pub struct StackedPattern {
    pub rows: Vec<LinearPattern>,
    pub text: Option<String>,
}

A stacked / multi-row 1D barcode. Each row carries its own LinearPattern; the renderer draws them top-to-bottom with a one- module spacer between rows.

Fields

rows: Vec<LinearPattern>

Rows, top to bottom. All rows must share the same total_width().

text: Option<String>

Optional human-readable text rendered below the entire symbol.

Implementations

impl StackedPattern

pub fn new( rows: Vec<LinearPattern>, text: Option<String>, ) -> Result<Self, (u32, u32)>

Build a StackedPattern from a non-empty vec of rows. Verifies that every row has the same total width (returns the first mismatch as an Err of (expected, got) for the caller to report).

pub fn width(&self) -> u32

Width of one row in modules (all rows share this width).

pub fn height_rows(&self) -> usize

Number of rows.
