Struct ScalarBoolean 

pub struct ScalarBoolean;

Portable scalar boolean reference.

Not a production provider: O(n·m), and it refuses interpenetrating surfaces. Registered at low priority so a real provider always wins dispatch; it exists to be the thing conformance is judged against.

Implementations

impl ScalarBoolean

pub const ID: BackendId

Stable identity for this reference implementation.

pub fn new() -> Self

Construct the reference provider.

Trait Implementations

impl Backend for ScalarBoolean

fn descriptor(&self) -> BackendDescriptor

Runtime descriptor and capability inventory.

impl Clone for ScalarBoolean

fn clone(&self) -> ScalarBoolean

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ScalarBoolean

impl Debug for ScalarBoolean

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

Formats the value using the given formatter.

impl Default for ScalarBoolean

fn default() -> ScalarBoolean

Returns the “default value” for a type.

impl MeshBoolean for ScalarBoolean

fn scratch_requirement(&self) -> ScratchRequirement

Exact, so no filter escalation and no scratch beyond the output.

fn cancellation_granularity(&self) -> CancellationGranularity

Checked per triangle pair, which is the inner loop of the O(n·m) scan.

fn boolean( &self, subject: &TriMesh, tool: &TriMesh, operation: BooleanOperator, options: &ExecutionOptions, ) -> GeomResult<BooleanOutcome>

Apply one regularized set operation.

fn determinism(&self) -> Determinism

Reproducibility this provider guarantees for its results.

fn solid_requirements(&self) -> SolidRequirements

Admissibility this provider requires of its operands.

fn subtract_many( &self, subject: &TriMesh, tools: &[TriMesh], options: &ExecutionOptions, ) -> Result<BooleanOutcome, GeomError>

Subtract many tools in one batch so implementations can union or schedule cutters efficiently. The default is correct but deliberately simple.

fn union_many( &self, solids: &[TriMesh], options: &ExecutionOptions, ) -> Result<BooleanOutcome, GeomError>

Union many solids in one batch so implementations can choose a reduction order.
