A kernel failure.

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.

Construction(Cause)

Arguments cannot produce the requested entity: three collinear points for a circle, a zero-length direction, a self-intersecting wire.

Domain(Cause)

An argument lies outside the domain the operation is defined on.

Range(Cause)

A parameter or index lies outside its valid range.

Dimension(Cause)

Collections or geometries that had to agree in size or dimension did not.

NullObject(Cause)

An operation was handed a null or empty shape where one was required.

Dangling(Cause)

A key did not resolve: most often a stale arena key, or a shape used with an arena that does not own it.

Numeric(Cause)

A numerical method failed: no convergence, a singular system, a step that could not be taken.

NotDone(Cause)

The algorithm ran but could not produce a result. Distinct from OgeomError::Construction: the inputs were legitimate and the failure is the algorithm’s.

Invariant(Cause)

The result exists but violates an invariant from docs/DATA_MODEL.md: tolerance containment, orientation consistency, edge representation agreement. Never returned silently; producing invalid topology is worse than failing.

Cancelled

Cancelled through a progress sink.

Unimplemented(Cause)

Reached a path that exists but has not been implemented yet.

Implementations

impl OgeomError

pub const fn is_tolerance_sensitive(&self) -> bool

Whether retrying with a looser tolerance could plausibly succeed.

Used by the fuzzy-tolerance escape hatch: numerical failures are worth retrying, malformed input is not.

Trait Implementations

impl Clone for OgeomError

fn clone(&self) -> OgeomError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OgeomError

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

Formats the value using the given formatter.

impl Display for OgeomError

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

Formats the value using the given formatter.

impl Eq for OgeomError

impl Error for OgeomError

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 OgeomError

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