Enum slint::Brush

#[non_exhaustive]
pub enum Brush {
    SolidColor(Color),
    LinearGradient(LinearGradientBrush),
    RadialGradient(RadialGradientBrush),
}
Expand description

A brush is a data structure that is used to describe how a shape, such as a rectangle, path or even text, shall be filled. A brush can also be applied to the outline of a shape, that means the fill of the outline itself.

Variants (Non-exhaustive)ยง

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
ยง

SolidColor(Color)

The color variant of brush is a plain color that is to be used for the fill.

ยง

LinearGradient(LinearGradientBrush)

The linear gradient variant of a brush describes the gradient stops for a fill where all color stops are along a line thatโ€™s rotated by the specified angle.

ยง

RadialGradient(RadialGradientBrush)

The radial gradient variant of a brush describes a circle variant centered in the middle

Implementationsยง

If the brush is SolidColor, the contained color is returned. If the brush is a LinearGradient, the color of the first stop is returned.

Returns true if this brush contains a fully transparent color (alpha value is zero)

assert!(Brush::default().is_transparent());
assert!(Brush::SolidColor(Color::from_argb_u8(0, 255, 128, 140)).is_transparent());
assert!(!Brush::SolidColor(Color::from_argb_u8(25, 128, 140, 210)).is_transparent());

Returns true if this brush is fully opaque

assert!(!Brush::default().is_opaque());
assert!(!Brush::SolidColor(Color::from_argb_u8(25, 255, 128, 140)).is_opaque());
assert!(Brush::SolidColor(Color::from_rgb_u8(128, 140, 210)).is_opaque());

Returns a new version of this brush that has the brightness increased by the specified factor. This is done by calling Color::brighter on all the colors of this brush.

Returns a new version of this brush that has the brightness decreased by the specified factor. This is done by calling Color::darker on all the color of this brush.

Returns the interpolated value between self and target_value according to the progress parameter t thatโ€™s usually between 0 and 1. With certain animation easing curves it may over- or undershoot though.
This method tests for self and other values to be equal, and is used by ==.
This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Anyโ€™s vtable from &Traitโ€™s.
