Struct DroppedRing 

#[non_exhaustive]
pub struct DroppedRing {
    pub operand: OverlayOperand,
    pub polygon: usize,
    pub ring: RingRole,
    pub reason: DropReason,
    pub area: f64,
    pub area_bound: f64,
}

One input ring an operation left out, and why.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

operand: OverlayOperand

The operand the ring belonged to.

polygon: usize

The index of its polygon in the operand; for crate::union_soup_with, the index of the ring.

ring: RingRole

Which ring of that polygon it was.

reason: DropReason

Why it was dropped.

area: f64

The magnitude of its signed area, computed exactly and rounded once for output. For a dropped outer ring, the area the operand lost; for a dropped hole, the area it gained.

area_bound: f64

A proven upper bound on the exact magnitude of its signed area.
