use qrcode::canvas::{Canvas, MaskPattern};

let mut c = Canvas::new(Version::Normal(1), EcLevel::L);

c.draw_data(b"data_here", b"ec_code_here");

Structs

Canvas

Canvas is an intermediate helper structure to render error-corrected data into a QR code.

Enums

MaskPattern	The mask patterns. Since QR code and Micro QR code do not use the same pattern number, we name them according to their shape instead of the number.
Module	The color of a module (pixel) in the QR code.

Functions

is_functional

Gets whether the module at the given coordinates represents a functional module.
