Errors produced by geometry operations.

Geometry functions never panic on bad input; they return one of these explicit results instead (non-finite numbers, degenerate shapes, unsupported transforms, …).

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.

NonFinite(&'static str)

An input coordinate or parameter was NaN or infinite.

Degenerate(&'static str)

The shape has no extent where one is required (zero-length segment, zero radius, …).

SingularTransform

The transform has a (near) zero determinant and cannot be inverted.

Fields

determinant: f64

Determinant of the linear part.

UnsupportedTransform

The transform cannot be applied while keeping the shape’s semantics (for example a non-uniform scale applied to a circle).

Fields

shape: &'static str

Shape kind name.

reason: &'static str

Human readable reason.

UnsupportedOperation

The requested operation is not defined for this shape kind.

Fields

operation: &'static str

Operation name.

shape: &'static str

Shape kind name.

NoBoundary(&'static str)

No intersection or boundary was found where the operation needs one.

InvalidArgument(&'static str)

A parameter is outside its valid range.

DimensionMismatch

Two quantities with different physical dimensions were combined.

Fields

left: String

Left operand dimension.

right: String

Right operand dimension.

UnknownUnit(String)

A unit string could not be parsed.

Trait Implementations

impl Clone for GeometryError

fn clone(&self) -> GeometryError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GeometryError

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

Formats the value using the given formatter.

impl Display for GeometryError

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

Formats the value using the given formatter.

impl Error for GeometryError

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 GeometryError

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