Struct CALayerBuilder 

pub struct CALayerBuilder { /* private fields */ }

Builder for CALayer.

let layer = CALayerBuilder::new()
    .bounds(CGRect::new(CGPoint::ZERO, CGSize::new(100.0, 100.0)))
    .position(CGPoint::new(50.0, 50.0))
    .background_color(Color::DARK_GRAY)
    .corner_radius(8.0)
    .build();

Implementations

impl CALayerBuilder

pub fn new() -> Self

Creates a new builder with default values.

pub fn bounds(self, bounds: CGRect) -> Self

Sets the bounds rectangle.

pub fn position(self, position: CGPoint) -> Self

Sets the position in superlayer coordinates.

pub fn background_color(self, color: impl Into<CFRetained<CGColor>>) -> Self

Sets the background color.

Accepts any type that implements Into<CFRetained<CGColor>>, including:

• Color::RED, Color::rgb(1.0, 0.0, 0.0)
• CFRetained<CGColor> directly

Example

.background_color(Color::BLUE)
.background_color(Color::rgb(0.2, 0.2, 0.2))
.background_color(Color::WHITE.with_alpha(0.5))

pub fn background_rgba( self, r: CGFloat, g: CGFloat, b: CGFloat, a: CGFloat, ) -> Self

Sets the background color from RGBA values (0.0–1.0).

pub fn corner_radius(self, radius: CGFloat) -> Self

Sets the corner radius.

pub fn hidden(self, hidden: bool) -> Self

Sets whether the layer is hidden.

pub fn transform(self, transform: CATransform3D) -> Self

Sets the 3D transform.

pub fn opacity(self, opacity: f32) -> Self

Sets the opacity (0.0–1.0).

pub fn build(self) -> Retained<CALayer>

Builds and returns the configured CALayer.

Trait Implementations

impl Default for CALayerBuilder

fn default() -> CALayerBuilder

Returns the “default value” for a type.
