Enum Module 

pub enum Module {
    Empty,
    Masked(Color),
    Unmasked(Color),
}

The color of a module (pixel) in the QR code.

Variants

Empty

The module is empty.

Masked(Color)

The module is of functional patterns which cannot be masked, or pixels which have been masked.

Unmasked(Color)

The module is of data and error correction bits before masking.

Implementations

impl Module

pub fn is_dark(self) -> bool

Checks whether a module is dark.

pub fn mask(self, should_invert: bool) -> Module

Apply a mask to the unmasked modules.

use qrcode_core::canvas::Module;
use qrcode_core::types::Color;

assert_eq!(Module::Unmasked(Color::Light).mask(true), Module::Masked(Color::Dark));
assert_eq!(Module::Unmasked(Color::Dark).mask(true), Module::Masked(Color::Light));
assert_eq!(Module::Unmasked(Color::Light).mask(false), Module::Masked(Color::Light));
assert_eq!(Module::Masked(Color::Dark).mask(true), Module::Masked(Color::Dark));
assert_eq!(Module::Masked(Color::Dark).mask(false), Module::Masked(Color::Dark));
