Struct Gradient 

pub struct Gradient {
    pub gradient_type: GradientType,
    pub rotation: f64,
    pub color_stops: Vec<ColorStop>,
}

Gradient definition for coloring QR code elements.

Fields

gradient_type: GradientType

Type of gradient (linear or radial).

rotation: f64

Rotation angle in radians (for linear gradients).

color_stops: Vec<ColorStop>

Color stops defining the gradient.

Implementations

impl Gradient

pub fn linear(color_stops: Vec<ColorStop>) -> Self

Create a new linear gradient.

pub fn linear_rotated(rotation: f64, color_stops: Vec<ColorStop>) -> Self

Create a new linear gradient with rotation.

pub fn radial(color_stops: Vec<ColorStop>) -> Self

Create a new radial gradient.

pub fn simple_linear(start: Color, end: Color) -> Self

Create a simple two-color linear gradient.

pub fn simple_radial(center: Color, edge: Color) -> Self

Create a simple two-color radial gradient.

Trait Implementations

impl Clone for Gradient

fn clone(&self) -> Gradient

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Gradient

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

Formats the value using the given formatter.

impl Default for Gradient

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Gradient

fn eq(&self, other: &Gradient) -> 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.
