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.

InvalidFrame

NonFinitePoint

RingTooShort

RepeatedVertex

ZeroArea

SelfIntersection

Non-adjacent boundary segments meet or cross.

HoleOutsideOuter

A hole is not inside its outer ring: it lies outside it or crosses it.

InvalidOffsetDistance

An offset distance or stroke width was not finite, or a width was not positive. A non-finite distance cannot produce a bounded region.

InvalidOffsetStyle

A join or cap parameter was not a finite positive value.

Separate from OverlayError::InvalidOffsetDistance because the fix is different: the caller passed a malformed style, not a malformed measure.

ZeroRadiusArc

An arc edge’s implied radius was not above tolerance.

Distinct from OverlayError::RepeatedVertex: the chord can be long enough while the bulge still implies a radius too small to be a real boundary. Such an edge is a point, not an arc.

HolesOverlap

Two holes of one polygon of a Region overlap: one crosses, holds or repeats the other (#448). Holes may touch at points and along a stretch they share.

PolygonsOverlap

Two polygons of a Region overlap: a point lies in both (#448). Polygons may touch at points and along a stretch they share.

impl Eq for OverlayError

impl Error for OverlayError

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

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
