Struct SheetLayout2D

A single packed sheet layout produced by the solver.

Fields

sheet_name: String

Name of the sheet type consumed by this layout.

width: u32

Sheet width.

height: u32

Sheet height.

cost: f64

Cost of consuming this sheet.

placements: Vec<Placement2D>

Rectangles placed on this sheet.

used_area: u64

Total area occupied by the placements.

waste_area: u64

Total wasted area on this sheet.

kerf_area: u64

Area lost to kerf on this sheet. Included in waste_area; reported separately so callers can distinguish kerf loss from unused area.

largest_usable_drop_area: u64

Area of the single largest axis-aligned rectangle of unused space on this sheet whose width and height both satisfy >= options.min_usable_side. Zero if no such rectangle exists.

sum_sq_usable_drop_areas: u128

Sum of area² over a canonical disjoint partition of this sheet’s free region, restricted to rectangles passing min_usable_side. Rewards consolidation: for positive a, b, a² + b² < (a+b)², so merging two adjacent drops into one strictly increases the sum.

Trait Implementations

impl Clone for SheetLayout2D

fn clone(&self) -> SheetLayout2D

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SheetLayout2D

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SheetLayout2D

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SheetLayout2D

fn eq(&self, other: &SheetLayout2D) -> 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 Serialize for SheetLayout2D

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
