What a picture is made of, for rasterize_layers: Shapes, plus what only a picture can show.

Variants (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.

Shape(Shape)

A filled and/or outlined shape.

Gradient

An outline filled from one color at the top to another at the bottom.

Fields

path: Vec<PathSegment>

Its outline.

top: (f32, Color)

Where the first color is whole, and that color.

bottom: (f32, Color)

Where the last color is whole, and that color.

Dashed

An outline drawn in dashes.

Fields

path: Vec<PathSegment>

Its outline.

width: f32

How wide the line is.

dash: f32

How long each dash and each gap is.

color: Color

Its color.

Clipped

Another layer, seen only inside a rectangle. Outputs that only write shapes write it whole.

Fields

rect: Rect

Where it shows.

layer: Box<Layer>

What shows.

Implementations

impl Layer

pub fn bounds(&self) -> Option<Rect>

A box it stays inside of, once drawn, or None if it draws nothing.

pub fn to_shape(&self) -> Shape

The closest a plain Shape gets, for outputs that only write shapes.

Trait Implementations

impl Clone for Layer

fn clone(&self) -> Layer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Layer

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

Formats the value using the given formatter.

impl PartialEq for Layer

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

Equality operator ==.
