Why a boolean step could not be carried out exactly.

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.

UnsupportedSection

Two faces’ supports intersect in a curve this stage does not take (anything but a line, circle or ellipse).

UnsupportedTrim

A face is trimmed by an edge or pcurve family this stage cannot intersect or classify against.

Undecided

A point was too close to a face boundary to classify.

Evaluation

A curve or surface could not be evaluated or inverted.

DanglingReference

A handle referenced missing geometry.

Measure(ExactMeasureError)

A face domain could not be built.

UnsupportedSplit

A face whose surface, or a section on it, has no exact pcurve in this stage.

UnclosedSplit

The pieces of a split face do not close into loops.

TangentSplit

Two pieces leave a vertex of a split face in the same direction and bend alike there, so no order between them can be read off.

EmptyResult

The operation leaves nothing: an intersection of solids that only touch, or a difference that removes everything. An exact B-rep cannot be empty, so this is the answer, not a refusal.

AmbiguousCavity

A cavity of the result lies inside none of its solids.

Assembly

The kept faces did not sew into a valid exact B-rep.

Trait Implementations

impl Clone for BooleanError

fn clone(&self) -> BooleanError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BooleanError

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

Formats the value using the given formatter.

impl Display for BooleanError

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

Formats the value using the given formatter.

impl Error for BooleanError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for BooleanError

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