Trait for geometric shapes that can be nested or packed.

Required Associated Types

type Scalar: RealField + Copy

The coordinate type (f32 or f64).

Required Methods

fn id(&self) -> &GeometryId

Returns the unique identifier for this geometry.

fn quantity(&self) -> usize

Returns the quantity of this geometry to place.

fn measure(&self) -> Self::Scalar

Returns the area (2D) or volume (3D) of this geometry.

fn aabb_vec(&self) -> (Vec<Self::Scalar>, Vec<Self::Scalar>)

Returns the axis-aligned bounding box as Vec (for generic dimension support).

fn centroid(&self) -> Vec<Self::Scalar>

Returns the centroid (center of mass) of this geometry.

fn validate(&self) -> Result<()>

Validates the geometry and returns an error if invalid.

fn rotation_constraint(&self) -> &RotationConstraint<Self::Scalar>

Returns the allowed rotations for this geometry.

Provided Methods

fn aabb(&self) -> ([Self::Scalar; 2], [Self::Scalar; 2])

Returns the axis-aligned bounding box as (min, max) corners.

fn allow_mirror(&self) -> bool

Returns whether mirroring/flipping is allowed.

fn priority(&self) -> i32

Returns optional priority for placement order (higher = placed first).

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
