Struct BackgroundOptions 

pub struct BackgroundOptions {
    pub color: Color,
    pub gradient: Option<Gradient>,
    pub round: f64,
}

Options for styling QR code background.

Fields

color: Color

Solid color for background (ignored if gradient is set).

gradient: Option<Gradient>

Optional gradient for background.

round: f64

Corner radius ratio (0.0 to 1.0, where 0.5 = fully rounded).

Implementations

impl BackgroundOptions

pub fn new(color: Color) -> Self

Create new background options with a specific color.

pub fn transparent() -> Self

Create transparent background.

pub fn with_color(self, color: Color) -> Self

Set the color.

pub fn with_gradient(self, gradient: Gradient) -> Self

Set the gradient.

pub fn with_round(self, round: f64) -> Self

Set the corner radius ratio.

Trait Implementations

impl Clone for BackgroundOptions

fn clone(&self) -> BackgroundOptions

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BackgroundOptions

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for BackgroundOptions

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for BackgroundOptions

fn eq(&self, other: &BackgroundOptions) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
