Enum ShadowPrimitive 

pub enum ShadowPrimitive {
    Drop {
        shape: Box<DrawPrimitive>,
        cutout: Option<Box<DrawPrimitive>>,
        blur_radius: f32,
        blend_mode: BlendMode,
    },

        fill: Box<DrawPrimitive>,
        cutout: Box<DrawPrimitive>,
        blur_radius: f32,

        clip_rect: Rect,
    },
}

A shadow that needs blur processing. Each renderer chooses how to blur. See DrawPrimitive::Shadow.

Variants

Drop

Drop shadow: render shape behind content, blurred. cutout knocks the element’s own (unoffset) shape out of the silhouette before the blur so translucent surfaces never sample their own shadow.

Fields

shape: Box<DrawPrimitive>

The shape drawn and blurred behind the content.

cutout: Option<Box<DrawPrimitive>>

Some cuts the element’s own unoffset shape out of the silhouette before the blur.

blur_radius: f32

Blur radius of the shadow, in logical pixels.

blend_mode: BlendMode

How the shadow combines with what is already drawn.

Inner

Inner shadow: render fill + cutout to offscreen, blur, clip to bounds.

Fields

fill: Box<DrawPrimitive>

The shape drawn and blurred to make the shadow.

cutout: Box<DrawPrimitive>

The shape cut out of the shadow’s silhouette, so it appears only outside that shape.

blur_radius: f32

Blur radius of the shadow, in logical pixels.

blend_mode: BlendMode

How the shadow combines with what is already drawn.

clip_rect: Rect

Element bounds — blurred result must be clipped here.

Trait Implementations

impl Clone for ShadowPrimitive

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ShadowPrimitive

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

Formats the value using the given formatter.

impl PartialEq for ShadowPrimitive

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

Equality operator ==.

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

Inequality operator !=.

impl RenderHash for ShadowPrimitive

fn render_hash(&self) -> u64
