Enum DropReason

Source

#[non_exhaustive]pub enum DropReason {
    TooShort,
    RepeatedVertex,
    ZeroArea,
    OuterDropped,
}

Expand description

Why a ring was dropped.

Variants (Non-exhaustive)§

This enum is marked as 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.

§

TooShort

Fewer than three points (OverlayError::RingTooShort).

§

RepeatedVertex

An edge no longer than the tolerance (OverlayError::RepeatedVertex).

§

ZeroArea

An area of at most tolerance.linear()^2, decided exactly (OverlayError::ZeroArea).

§

OuterDropped

A hole, valid on its own, whose outer ring was dropped.
