Enum Shape 

pub enum Shape {
    RoundedRectangle {
        top_left: RoundedCorner,
        top_right: RoundedCorner,
        bottom_right: RoundedCorner,
        bottom_left: RoundedCorner,
    },
    Ellipse,
}

Shape definitions for UI components.

Shape is used by multiple components (surface, fluid_glass, sliders, progress, buttons) to define visual outline, hit-testing, and pipeline behavior.

Variants

• Shape::RoundedRectangle – Per-corner capsule or manual radius + per-corner G2
• Shape::Ellipse – Ellipse filling the component bounds

Example

use tessera_ui::dp::Dp;
use tessera_ui_basic_components::shape_def::{RoundedCorner, Shape};

// Explicit rounded rectangle
let rr = Shape::RoundedRectangle {
    top_left: RoundedCorner::manual(Dp(8.0), 3.0),
    top_right: RoundedCorner::manual(Dp(8.0), 3.0),
    bottom_right: RoundedCorner::manual(Dp(8.0), 3.0),
    bottom_left: RoundedCorner::manual(Dp(8.0), 3.0),
};

// Ellipse
let ellipse = Shape::Ellipse;

// Mixed capsule/fixed corners (left side capsule, right side explicit)
let mixed = Shape::RoundedRectangle {
    top_left: RoundedCorner::Capsule, // auto radius = min(width, height) / 2
    top_right: RoundedCorner::manual(Dp(8.0), 3.0),
    bottom_right: RoundedCorner::manual(Dp(8.0), 3.0),
    bottom_left: RoundedCorner::Capsule, // also capsule
};

Variants

RoundedRectangle

Rounded rectangle with per-corner capsule or manual radius + G2.

Fields

top_left: RoundedCorner

Top-left corner definition.

top_right: RoundedCorner

Top-right corner definition.

bottom_right: RoundedCorner

Bottom-right corner definition.

bottom_left: RoundedCorner

Bottom-left corner definition.

Ellipse

Ellipse fitting the component bounds.

Implementations

impl Shape

pub const RECTANGLE: Self

A pure rectangle shape with no rounded corners.

pub const fn rounded_rectangle(radius: Dp) -> Self

A helper to create a uniform rounded rectangle shape with manual corners.

pub const fn capsule() -> Self

A helper to create a uniform capsule on all corners.

pub fn resolve_for_size(self, size: PxSize) -> ResolvedShape

Resolves a shape into pixel radii and per-corner G2 parameters for a given size.

Trait Implementations

impl Clone for Shape

fn clone(&self) -> Shape

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Shape

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

Formats the value using the given formatter.

impl Default for Shape

fn default() -> Self

Returns the default shape, which is a rectangle with zero corner radius.

Example

use tessera_ui::dp::Dp;
use tessera_ui_basic_components::shape_def::{RoundedCorner, Shape};
let default_shape = Shape::default();
assert_eq!(
    default_shape,
    Shape::RoundedRectangle {
        top_left: RoundedCorner::manual(Dp(0.0), 3.0),
        top_right: RoundedCorner::manual(Dp(0.0), 3.0),
        bottom_right: RoundedCorner::manual(Dp(0.0), 3.0),
        bottom_left: RoundedCorner::manual(Dp(0.0), 3.0),
    }
);

impl PartialEq for Shape

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

impl Copy for Shape

impl StructuralPartialEq for Shape
